Description

Technical Field

[0001] This utility model relates to the technical field of sweepers, and in particular to an automatic dust removal device for sweepers. Background Technology

[0002] Robotic sweepers require regular manual cleaning of the dust collection box, which is cumbersome and can easily cause secondary pollution. During the sweeping process, the high-speed rotation of the roller brush causes dust on the floor to be stirred up. Most of the dust is swept into the dust box, while a small portion remains as dust and falls onto the surface of the sweeper. Over time, this dust accumulates on the surface of the sweeper, especially on the control panel, causing secondary pollution.

[0003] While robotic vacuum cleaners with built-in dust collection stations have emerged on the market, enabling automatic dust collection, current dust collection stations typically only focus on cleaning the dust inside the vacuum cleaner's internal dustbin, neglecting the issue of cleaning dust from the vacuum cleaner's surface. Over time, a large amount of dust accumulates on the vacuum cleaner's surface, affecting not only its appearance but also potentially impacting sensor sensitivity and operational efficiency.

[0004] Therefore, there is an urgent need for an automatic dust removal device that can collect dust automatically while also cleaning the surface of the sweeper. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The technical problem to be solved by this utility model is to provide an automatic dust removal device for sweeping machines. By setting an exhaust structure at the outlet of the dust collection fan, the airflow at the outlet of the dust collection fan during the dust collection process is guided to the surface of the sweeping machine, thereby realizing automatic dust removal on the surface of the sweeping machine. This solves the problem that dust on the surface of the sweeping machine needs to be cleaned manually in the prior art, improves the user experience, and extends the service life of the sweeping machine.

[0007] (II) Technical Solution

[0008] The solution adopted by this utility model to solve the above-mentioned technical problems is an automatic dust removal device for a sweeper, including...

[0009] A dust collection base station, which has a storage space for accommodating a sweeping machine;

[0010] A dust collection fan, located inside the dust collection base station, is used to extract dust from the dust box of the sweeper.

[0011] An exhaust structure, located at the outlet of the dust collection fan, is used to spray the gas discharged from the outlet of the dust collection fan onto the surface of the sweeper placed in the receiving space.

[0012] In some embodiments, the outlet of the dust collection fan is connected to an air guide system, so that the gas discharged by the dust collection fan while collecting dust is guided by the air guide system in the sealed cavity and discharged from the exhaust structure of the outlet of the dust collection fan, and blown towards the upper surface and other surfaces of the sweeper; after being impacted by the strong airflow, the dust accumulated on the surface of the sweeper is cleaned away.

[0013] By adopting the above solution, an exhaust structure is set at the outlet of the dust collection fan to guide the airflow from the outlet of the dust collection fan to the surface of the sweeper during the dust collection process, thereby realizing automatic dust removal from the surface of the sweeper. This solves the problem that the dust on the surface of the sweeper needs to be cleaned manually in the existing technology, improves the user experience, and extends the service life of the sweeper.

[0014] In some embodiments, the dust collecting fan is positioned above the receiving space; the exhaust structure is located at the bottom of the dust collecting fan and above the receiving space, and is used to spray the gas discharged from the outlet of the dust collecting fan toward the upper surface of the sweeper placed in the receiving space.

[0015] By adopting the above solution, the dust collection fan is positioned above the housing space to improve space utilization; the exhaust structure is located at the bottom of the dust collection fan to ensure that the airflow is directly sprayed onto the upper surface of the sweeper, thereby achieving automatic dust removal from the upper surface of the sweeper and solving the problem of traditional dust collection stations neglecting dust on the machine surface.

[0016] In some embodiments, the outlet of the dust collection fan is located close to the receiving space, and the outlet of the dust collection fan is detachably connected to a fan bottom cover, the fan bottom cover being provided with an exhaust structure for connecting the outlet of the dust collection fan and the receiving space.

[0017] The above scheme features a detachable fan bottom cover for easy maintenance and cleaning; the dust collection fan outlet is positioned close to the receiving space, shortening the airflow path and improving dust removal efficiency; the fan bottom cover connects the outlet and the receiving space to form a complete air path system.

[0018] In some embodiments, the exhaust structure includes an exhaust port provided on the lower cover of the fan.

[0019] In some embodiments, a plurality of exhaust vents are provided, and the plurality of exhaust vents are arranged at intervals on the lower cover of the fan.

[0020] By adopting the above scheme, multiple exhaust holes are set to increase the exhaust area and improve dust removal efficiency; through the interval arrangement, the airflow is evenly distributed, ensuring a wider cleaning coverage.

[0021] In some embodiments, the exhaust port is shaped as one or more combinations of circles, ellipses, elongated shapes, or polygons to meet different airflow requirements and dust removal effects.

[0022] In some embodiments, the dust collection fan is provided with an air inlet and an air outlet arranged opposite to each other, the air inlet and the air outlet are distributed along the axial direction, and the air outlet is arranged close to the receiving space, while the air inlet is arranged above the air outlet.

[0023] By adopting the above scheme, the axial distribution relationship of the fan's inlet and outlet ends is clarified, and the airflow path is optimized; the inlet end is set at the top to avoid dust backflow and contamination of the cleaned area; the outlet end is close to the containment space to reduce pipeline losses and improve efficiency.

[0024] In some embodiments, the dust collection base station includes a base and a base station body disposed on the base. The base station body and the base are spaced apart to form the receiving space. Furthermore, the front end of the receiving space has an opening for a sweeping machine to enter, and the rear end of the receiving space has a docking part for docking with the sweeping machine.

[0025] The above design allows the front opening of the storage space to facilitate the entry and exit of the sweeper; the rear docking section ensures a precise connection with the sweeper, improving dust removal efficiency.

[0026] In some embodiments, the base is inclined from bottom to top from the front end of the receiving space toward the rear end of the receiving space; this improves the effect of the airflow discharged from the exhaust port on the automatic dust removal of the sweeper surface.

[0027] In some embodiments, an air extraction channel is formed between the docking part and the dust collection fan.

[0028] Specifically, after the sweeper completes its cleaning work, it automatically returns to the dust collection station's containment space and docks. Once the dust collection fan starts, it draws dust from the sweeper's dustbin through the extraction channel; simultaneously, the fan's exhaust port blows airflow onto the sweeper's surface through the exhaust structure, thus blowing away dust. This achieves dual cleaning of both the sweeper's internal dustbin and external surface, improving cleaning efficiency, reducing manual intervention, and extending the sweeper's lifespan.

In some embodiments, the shape of the exhaust holes 301 is one or more combinations of circles, ellipses, elongated shapes, or polygons to meet different airflow requirements and dust removal effects.

[0054] In some embodiments, the dust collecting fan 200 is provided with an inlet end 201 and an outlet end 202 arranged opposite to each other. The inlet end 201 and the outlet end 202 are distributed along the axial direction, and the outlet end 202 is located close to the receiving space 101, while the inlet end 201 is positioned above the outlet end 202.

[0055] In some embodiments, the dust collection base station 100 includes a base 102 and a base station body 103 disposed on the base 102. The base station body 103 and the base 102 are spaced apart to form the receiving space 101. The receiving space 101 has an opening 104 at its front end for a sweeper 10 to enter, and a docking part 105 at its rear end for docking with the sweeper 10. With this design, the front opening 104 of the receiving space 101 facilitates the entry and exit of the sweeper 10; the rear docking part 105 ensures precise connection with the sweeper 10, improving dust removal efficiency. In some embodiments, the base 102 is inclined upwards from the front end of the receiving space 101 towards the rear end, improving the automatic dust removal effect of the airflow discharged from the exhaust port 301 on the surface of the sweeper 10. In some embodiments, an air extraction channel 500 is formed between the docking part 105 and the dust collection fan 200.

[0056] The working principle of this utility model:

[0057] After the sweeper 10 completes its cleaning work, it automatically returns to the receiving space 101 of the dust collection base station 100 and docks with it. After the dust collection fan 200 starts, it extracts dust from the dust box of the sweeper 10 through the suction channel 500; simultaneously, the exhaust end 202 of the dust collection fan 200 sprays airflow onto the surface of the sweeper 10 through the exhaust port 301 of the exhaust structure 300, thereby blowing away the dust from the surface of the sweeper 10. This achieves dual cleaning of the internal dust box and the external surface of the sweeper 10, improving cleaning efficiency, reducing manual intervention, and extending the service life of the sweeper 10.
