For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The following is combined Figures 1-4 This invention describes the specific implementation of the dust collection device of the cleaning equipment base station of this utility model.

[0027] This utility model provides a dust collection device for a cleaning equipment base station. By configuring a dust collection duct 10, a dust collection chamber 20, a dust collection fan 30, and a drying chassis, it achieves the functions of automatically removing dirt, efficiently filtering and purifying air, and rapidly drying the equipment. Figure 1As shown, the dust collection device of the cleaning equipment base station includes: a dust collection duct 10, in which the inlet end of the dust collection duct 10 is connected to the sewage outlet of the cleaning equipment when the cleaning equipment is configured in the base station; a dust collection chamber 20, connected to the outlet end of the dust collection duct 10, and equipped with a filter component inside; a dust collection fan 30, installed in the dust collection chamber 20, used to create a negative pressure environment in the dust collection chamber 20 during operation; and a drying chassis for the cleaning equipment in the base station, with the air outlet of the dust collection fan 30 leading to the drying chassis.

[0028] Specifically, one end of the dust collection duct 10 is connected to the drain outlet of the cleaning equipment, and the other end is connected to the dust collection chamber 20. When the cleaning equipment returns to the base station, the dust collection fan 30 starts, generating negative pressure inside the dust collection chamber 20. This draws the dirt from the cleaning equipment into the dust collection chamber 20 through the dust collection duct 10, achieving an automatic emptying process. The dust collection chamber 20 is equipped with a filter assembly that effectively intercepts and filters out dust and fine particles from the intake air, ensuring clean exhaust air and preventing secondary pollution. The base station is also equipped with a drying chassis, with the exhaust outlet of the dust collection fan 30 pointing directly to this chassis. After the cleaning equipment has finished emptying, the airflow generated by the dust collection fan 30 helps the bottom of the cleaning equipment dry quickly, achieving the reuse of air energy, reducing the growth of bacteria and mold caused by moisture, and extending the service life of the equipment. By integrating the above functions, users do not need to manually clean the dirt inside the equipment or perform drying. The entire process is highly automated, greatly facilitating daily use and reducing maintenance costs.

[0029] Furthermore, based on the above, a guide duct can be installed to direct the clean gas from the outlet of the dust collection fan 30 to the drying chassis below the base station. The guide duct allows for more precise control of the airflow direction and speed. The guide duct is preferably designed to be detachable or easy to clean, facilitating regular cleaning by the user to ensure smooth airflow and maintain the long-term stable operation of the base station.

[0030] Furthermore, according to the dust collection device of the cleaning equipment base station of this utility model, the dust collection fan 30 includes a fan box and a fan body disposed within the fan box; the fan box is sealed and connected to the top of the dust collection chamber 20; the air outlet of the dust collection fan 30 is a porous structure 31 disposed on one side of the fan box. Specifically, the fan body is installed inside the fan box and is responsible for generating airflow. The function of the fan box is to protect the fan body and provide a relatively sealed environment to ensure the stability and efficiency of airflow. The fan box is connected to the top of the dust collection chamber 20 by a sealed connection to prevent external air from entering the dust collection chamber 20, ensuring a negative pressure environment inside the dust collection chamber 20 and improving the efficiency of dirt collection. The air outlet of the dust collection fan 30 is designed as a porous structure 31, located on one side of the fan box. The porous structure 31 can be specifically configured as needed, for example, by changing the number and size of the holes to adjust the airflow intensity, adapting to the usage scenario and requirements.

[0031] Furthermore, according to the dust collection device of the cleaning equipment base station of this utility model, the outlet end of the dust collection duct 10 is connected to the bottom of the dust collection bin 20; the height of the inlet end of the dust collection duct 10 is higher than the height of the outlet end of the dust collection duct 10. Specifically, the outlet end of the dust collection duct 10 is directly connected to the bottom of the dust collection bin 20, and the inlet end of the dust collection duct 10 (the part connected to the sewage outlet of the cleaning equipment) is set higher than the outlet end (the part connected to the bottom of the dust collection bin 20) to prevent backflow of impurities. Specifically, due to gravity, impurities deposited at the bottom of the dust collection bin 20 will not flow back to the inlet end of the dust collection duct 10. Even when the dust collection fan 30 stops working, impurities will remain in the dust collection bin 20 due to the height difference and will not flow back into the cleaning equipment. The height difference design reduces the risk of dirt accumulation in the dust collection duct 10, keeps the duct unobstructed, and extends the service life of the equipment.

[0032] Currently, most smart cleaning equipment base station dust collection containers in the industry use disposable dust bags. Users need to replace these consumables based on usage frequency, resulting in low environmental benefits. Furthermore, as dust accumulates inside the dust bag (affecting ventilation), suction power decreases, impacting dust collection efficiency. Figure 2 As shown, a dust collection device for a cleaning equipment base station according to this utility model includes a filter assembly comprising a dust collection cup 21, inside which a cyclone filtration mechanism is provided. The dust collection cup 21 is cylindrical. The inlet of the dust collection cup 21 is located on one side of the dust collection cup 21 and is arranged tangentially relative to the cross-section of the dust collection cup 21. The outlet of the dust collection cup 21 is located at the top of the dust collection cup 21 and is connected to a dust collection fan 30. The dust collection cup 21 is designed to be reusable; users only need to empty the dust collection cup 21 periodically, reducing reliance on disposable dust bags and lowering resource consumption and environmental pollution. The cyclone filtration mechanism can continuously separate dust, maintain the suction power of the dust collection fan 30, avoid suction power reduction due to dust bag clogging, and ensure efficient dust collection for long-term use.

[0033] Specifically, the dust collection cup 21 is cylindrical, a shape that helps form a stable cyclone and improves filtration efficiency. Inside the dust collection cup 21 is a cyclone filtration mechanism that uses centrifugal force to separate dust and particulate matter from the air. When air enters the dust collection cup 21 at high speed, larger particles are thrown against the cup wall, sink along the wall, and deposit at the bottom, while lighter air continues to rise and exits through the top outlet of the dust collection cup 21. The inlet of the dust collection cup 21 is located on one side and is tangentially arranged relative to the cross-section of the dust collection cup 21, allowing the airflow entering the dust collection cup 21 to form a strong rotational motion along the cup wall, enhancing the centrifugal separation effect and improving filtration efficiency. Because the cyclone filtration mechanism can continuously and effectively separate dust, the suction power of the dust collection fan 30 does not decrease significantly over time, thus maintaining a high dust collection efficiency.

[0034] Furthermore, such as Figure 3 and Figure 4 As shown, according to the present invention, a dust collection device for a cleaning equipment base station includes a cyclone filtration mechanism comprising a primary filtration section. The primary filtration section includes a filter screen structure 22, which is cup-shaped. Multiple small filter holes are arrayed along the circumference of the filter screen structure 22 to block impurities larger than the pore size between the primary filtration section and the inner wall of the dust collection cup 21. The primary filtration section also includes a skirt structure 23 located below the filter screen structure 22. The skirt structure 23 is trumpet-shaped, with its wide-angle side facing the bottom of the dust collection cup 21. The small hole design of the filter screen structure 22 effectively blocks large particles, ensuring relatively clean air entering the dust collection fan 30 and improving overall filtration efficiency. The skirt structure 23 prevents impurities at the bottom of the dust collection cup 21 from being swept up by the airflow, avoiding secondary pollution and maintaining the cleanliness of the airflow.

[0035] Specifically, the filter structure 22 is cup-shaped with multiple small filter holes arranged in an array along its circumference. The pore size of these holes is designed to block impurities larger than the pore size, causing them to remain between the primary filtration section and the inner wall of the dust collection cup 21. The filter structure 22 effectively filters out larger particles of garbage and dust, preventing these large particles from directly entering the dust collection fan 30, reducing fan wear and clogging risks, and extending the fan's service life. The skirt structure 23 is trumpet-shaped, with its wide-angle side facing the bottom of the dust collection cup 21, helping to guide airflow and impurities downwards, ensuring that large particles can settle smoothly to the bottom of the dust collection cup 21. The main function of the skirt structure 23 is to allow impurities to fall to the bottom of the dust collection cup 21 through the gap between the skirt structure 23 and the inner wall of the dust collection cup 21, while preventing impurities at the bottom of the dust collection cup 21 from being swept up by the airflow to the skirt structure 23. This not only ensures smooth airflow but also prevents settled impurities from being re-raised, thus affecting the filtration effect.

[0036] Furthermore, according to the dust collection device of the cleaning equipment base station of this utility model, the cyclone filtration mechanism includes a secondary filtration section disposed inside the filter structure 22; the secondary filtration section includes a conical sleeve 24 and a cylinder 25 coaxially disposed inside the conical sleeve 24; the side wall of the conical sleeve 24 is provided with a first opening in the tangential direction, the conical end of the conical sleeve 24 is provided with a second opening facing downward, and the top opening of the cylinder 25 leads to the dust collection fan 30. The combined design of the filter structure 22 and the secondary filtration section realizes multi-stage filtration. First, large particulate impurities are blocked by the filter structure 22, and then fine particulate matter is further separated and purified by the conical sleeve 24 and the cylinder 25, ensuring that the air entering the dust collection fan 30 is clean.

[0037] Specifically, the conical sleeve 24 is located inside the filter structure 22, with a first tangential opening on its sidewall and a second downward-facing opening at the conical end. The first opening design allows airflow to enter the conical sleeve 24 tangentially, creating a strong vortex effect and further separating fine particulate matter from the air. The downward-facing second opening ensures that the separated fine particulate matter can settle smoothly to the bottom of the dust collection cup 21. The cylinder 25 forms a vortex space between the conical sleeve 24 and the cylinder 25. When airflow enters through the first tangential opening of the conical sleeve 24, a vortex is formed in the space between the conical sleeve 24 and the cylinder 25. Under the action of centrifugal force, fine particulate matter is thrown towards the inner wall of the conical sleeve 24 and settles along the inner wall to the bottom of the dust collection cup 21. The separated clean air enters the interior of the cylinder 25 through the opening at the bottom of the cylinder 25 and then flows along the cylinder 25 to the dust collection fan 30. Through this multi-stage filtration design, the base station of this invention can not only more effectively separate and collect impurities of different particle sizes, but also improve the stability and reliability of the overall system and enhance the user experience.

[0038] Furthermore, according to the dust collection device of the cleaning equipment base station of this utility model, the filter structure 22 is provided with multiple secondary filtration sections inside, each secondary filtration section including a conical sleeve 24 and a cylinder 25 coaxially disposed inside the conical sleeve 24. The combined design of the filter structure 22 and the multiple secondary filtration sections achieves multi-stage filtration. First, the filter structure 22 blocks large particulate impurities, and then the four secondary filtration sections further separate and purify fine particulate matter. The even distribution of the multiple secondary filtration sections forms multiple cyclone cones, each of which can independently generate a strong vortex effect, effectively separating fine particulate matter in the air and significantly improving the overall separation efficiency.

[0039] In a preferred embodiment, four secondary filtration sections are provided inside the filter structure 22. These four secondary filtration sections are evenly spaced in the horizontal direction to ensure that the airflow is evenly distributed throughout the filter structure 22, avoid the airflow from concentrating in one area, and improve the overall filtration efficiency.

[0040] Furthermore, according to the dust collection device of the cleaning equipment base station of this utility model, the filter assembly includes a three-stage filtration section; the three-stage filtration section preferably includes a HEPA filter 26 disposed inside the outlet of the dust collection cup 21. The HEPA filter 26 can capture more than 99.97% of particles larger than 0.3 micrometers, making it suitable for applications with high air quality requirements. The use of the HEPA filter 26 effectively filters out micro-dust and other fine particulate matter, ensuring that the final exhaust air is very clean.

[0041] In a preferred embodiment, the filter assembly includes a filter screen structure 22, multiple secondary filtration sections, and a HEPA filter 26 along the airflow path, thereby achieving multi-stage filtration. First, the filter screen structure 22 blocks large particulate impurities, then the multiple secondary filtration sections further separate and purify fine particulate matter, and finally the HEPA filter 26 filters out micro-dust to thoroughly clean the gas.

[0042] According to the preferred embodiment of the dust collection device for a cleaning equipment base station of this utility model, when cleaning the cleaning equipment, the cleaning tools (such as mops, roller brushes, etc.) of the cleaning equipment are first cleaned. Then, a dust collection command is issued, and the dust collection fan 30 starts working. The garbage in the dust box of the main unit of the cleaning equipment is collected into the dust collection cup 21 through the dust collection duct 10. The cyclone filtration mechanism inside the dust collection cup 21 includes a filter screen structure 22 and four evenly distributed secondary filtration sections. These secondary filtration sections form a quadruple cyclone cone inside the filter screen structure 22 to further separate and purify fine particulate matter. Finally, the garbage and dust that have passed through triple filtration (filter screen structure 22, secondary filtration sections, HEPA filter 26) are collected in the dust cup, and clean air is discharged from the exhaust port and guided to the drying chassis of the base station below to dry the cleaning tools, realizing the reuse of wind energy.

[0043] In the preferred embodiment, the dust collection cup 21, the primary filter, the secondary filter, and the tertiary filter are all installed in a detachable manner. This not only facilitates cleaning and maintenance, but also allows users to easily disassemble the dust collection cup 21, the filter structure 22, the four secondary filters, and the HEPA filter 26. Regularly emptying the dust, cleaning or replacing the filters ensures the cleanliness and efficient operation of each component, increases the service life of the system, reduces overall wear, and lowers maintenance costs.

[0044] like Figure 2 and Figure 4As shown, according to the present invention, a dust collection device for a cleaning equipment base station includes a dust collection cup 21 with a bottom cover 27. The bottom cover 27 has an open state and a closed state. In the open state, the bottom cover 27 is wholly or partially detached from the dust collection cup 21 to release impurities remaining in the dust collection cup 21. In the closed state, the bottom cover 27 is sealed closed to the bottom of the dust collection cup 21. Specifically, the bottom cover 27 of the dust collection cup 21 is designed to be openable and closable. Users can easily open the bottom cover 27 to remove impurities from the dust collection cup 21. In the open state, the bottom cover 27 can be wholly or partially detached from the dust collection cup 21, ensuring that impurities in the dust collection cup 21 can be completely released and preventing residue. This design not only simplifies the cleaning process but also reduces the risk of contact and contamination for users during cleaning. In the closed state, the bottom cover 27 is sealed closed to the bottom of the dust collection cup 21, ensuring that no leakage occurs during dust collection, maintaining a good negative pressure environment, and improving dust collection efficiency. This openable and closable bottom cover design not only improves the user experience but also ensures the efficient operation and long-term stability of the base station.

[0045] Furthermore, according to the dust collection device of the cleaning equipment base station of this utility model, one end of the bottom cover 27 is hinged to the dust collection cup 21. On the side opposite to the hinge structure of the bottom cover 27, the dust collection cup 21 is provided with a snap-fit ​​structure 28 adapted to the other end of the bottom cover 27; and / or, a sealing ring 29 is provided on the side of the bottom cover 27 facing the dust collection cup 21. Specifically, the bottom cover 27 of the dust collection cup 21 is designed to be hinged to the dust collection cup 21 at one end. This hinge structure allows the bottom cover 27 to be opened and closed like a door. The user can easily open the bottom cover 27 by simply lifting or pressing it, making it convenient to remove impurities from the dust collection cup 21. On the side opposite to the hinge structure, the dust collection cup 21 is provided with a snap-fit ​​structure 28 adapted to the other end of the bottom cover 27, ensuring that the bottom cover 27 can be firmly fixed to the dust collection cup 21 in the closed state, preventing leakage during the dust collection process. In addition, a sealing ring 29 is provided on the side of the bottom cover 27 facing the dust cup 21, which further enhances the sealing performance of the bottom cover 27, ensures a good negative pressure environment during the dust collection process, and improves the dust collection efficiency.

[0046] This utility model also provides a cleaning equipment base station, including the dust collection device of the cleaning equipment base station described in the above embodiments. This base station achieves efficient and convenient dust collection and maintenance functions through the dust collection device. Specifically, the dust collection fan 30 draws debris from the dust box of the cleaning equipment main unit into the dust collection cup 21 through the dust collection duct 10. After triple filtration through the filter structure 22, the secondary filter section, and the HEPA filter 26, clean air is ensured to be discharged from the exhaust port and guided to the drying chassis of the base station below to dry the cleaning tools, thus reusing the airflow. The hinged and snap-fit ​​structure 28 of the bottom cover 27 allows users to easily open and close the cover to thoroughly remove impurities from the dust collection cup 21. This base station is suitable for various cleaning equipment, such as vacuum cleaners, floor scrubbers, and robotic vacuum cleaners, and can effectively improve the cleaning efficiency and user experience of these devices.
