Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a cleaning device and cleaning system. Background Technology

[0002] Vacuum cleaners typically consist of a main body containing dirt and a filter, a cleaning head connected to the main body and having a suction port, and a motor-driven suction unit that draws dirty air through the cleaning head into a dust cup. The dirty airflow is then directed to a separation device in the dust cup to separate dirt and dust from the air before it is released into the atmosphere. Vacuum cleaners usually have a pre-motor filter to filter the airflow entering the motor, extending its lifespan. In related technologies, cleaning devices can be docked with a base station to clean the dirt in the cleaning device's dust cup; however, the pre-motor filter cannot be effectively cleaned and requires frequent replacement.

Detailed Implementation

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] Combination Figure 1 and Figure 2 The cleaning device 100 according to an embodiment of the present utility model includes: a main unit 10, a dust cup 20 and a filter device 30.

[0037] The main unit 10 includes a suction motor 11, a dust cup 20 connected to the main unit 10, and at least a portion of the filter device 30 extending into the dust cup 20. Specifically, the suction motor 11 can be used to provide negative pressure. Under the action of negative pressure, the cleaning device 100 can suck dust, hair, and other dirt from the working surface into the dust cup 20, and the clean airflow filtered by the filter device 30 is discharged to the outside of the cleaning device 100 through the suction motor 11.

[0038] Combination Figure 2 The filtration device 30 includes a separation mechanism 31 and a motor pre-filter 32. The motor pre-filter 32 is located downstream of the separation mechanism 31 and upstream of the suction motor 11. It should be noted that in this application, "downstream" refers to the rear position along the airflow direction, that is, the last position the airflow passes through in the path from upstream (starting point) to downstream (end point). Specifically, the airflow containing dirt entering the dust cup 20 is first filtered by the separation mechanism 31, then filtered again by the motor pre-filter 32, and finally discharged to the outside of the cleaning equipment 100 by the suction motor 11. The motor pre-filter 32 is located downstream of the separation mechanism 31 and upstream of the suction motor 11. The motor pre-filter 32 can filter the airflow entering the suction motor 11, preventing dust, dirt, etc., from entering the suction motor 11, extending the service life of the suction motor 11, and preventing secondary pollution caused by the airflow discharged from the cleaning equipment 100.

[0039] The motor pre-filter 32 is rotatable. Understandably, after prolonged use, dust and other impurities accumulate in the motor pre-filter 32. If not cleaned promptly, this can clog the pores, weakening the suction of the cleaning device 100 and preventing effective airflow filtration, leading to dust entering the suction motor 11 and causing secondary pollution. The rotatable motor pre-filter 32 allows for centrifugal cleaning of the dust and other contaminants during rotation, achieving self-cleaning without requiring user disassembly. This reduces the user's workload, extends the lifespan of the suction motor 11, and solves the problem of frequent pre-filter replacements.

[0040] According to the cleaning device 100 of this utility model embodiment, the motor pre-filter 32 can filter the airflow entering the suction motor 11, thereby improving the service life of the suction motor 11. The motor pre-filter 32 is rotatable, which facilitates the cleaning of dust and other dirt on the motor pre-filter 32 during the rotation process, thereby achieving self-cleaning of the motor pre-filter 32, improving the service life of the motor pre-filter 32, and reducing the user's operating burden.

[0041] The rotation of the motor pre-filter 32 can be achieved in different ways. For example, the motor pre-filter 32 can be driven to rotate by a driving component. After the cleaning device 100 completes the cleaning work, the motor pre-filter 32 can be driven to rotate by the driving component. During the rotation, dust and other dirt attached to the motor pre-filter 32 are separated from the motor pre-filter 32 under the action of centrifugal force, thereby achieving the effect of cleaning the motor pre-filter 32. Alternatively, the motor pre-filter 32 can be driven to rotate by airflow. For example, the cleaning device 100 can be connected to the base station 200 and has a self-cleaning mode. In the self-cleaning mode, the base station 200 generates negative pressure in the dust cup 20 to clean the dirt in the dust cup 20. The motor pre-filter 32 can be driven to rotate by the airflow entering the dust cup 20. That is to say, in the self-cleaning mode, the airflow entering the dust cup 20 can clean the motor pre-filter 32 while cleaning the dust cup 20, without the need for an additional structure to clean the motor pre-filter 32, reducing the user's operating burden.

[0042] The cleaning equipment 100 of this utility model can be a vacuum cleaner, floor scrubber, sweeping robot, mite remover, etc. This utility model is mainly described using a vacuum cleaner as an example.

[0043] In some embodiments of this utility model, the cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the motor pre-filter 32 is stationary relative to the main unit 10. In the self-cleaning mode, the motor pre-filter 32 can rotate relative to the main unit 10. Specifically, in the working mode, the motor pre-filter 32 cannot rotate, so that the motor pre-filter 32 can stably filter the dust-laden airflow entering the suction motor 11 and avoid the rotation of the motor pre-filter 32 affecting the filtration effect. In the self-cleaning mode, the motor pre-filter 32 rotates relative to the main unit 10, so that the motor pre-filter 32 can clean the dust and other dirt attached to the motor pre-filter 32 during the rotation process.

[0044] For example, the cleaning device 100 can be connected to the base station 200. In self-cleaning mode, the base station 200 cleans the dirt in the dust cup 20. The motor pre-filter 32 can be rotated directly by the drive component set on the cleaning device 100 or the base station 200; or, the motor pre-filter 32 can be rotated by the airflow entering the dust cup 20 from the air inlet channel of the cleaning device 100; or, the separation mechanism 31 includes a rotatable first filter part 313, and the motor pre-filter 32 is connected to the first filter part 313. In self-cleaning mode, the first filter part 313 rotates and synchronously drives the motor pre-filter 32 to rotate.

[0045] Combination Figure 2 and Figure 3In some embodiments of this utility model, the dust cup 20 includes a cup body 21 and a cup lid 22. The cup body 21 is provided with a dust outlet 211, and the cup lid 22 is used to open and close the dust outlet 211. When the cleaning device 100 is vacuuming, the cup lid 22 can close the dust outlet 211 so that the filter device 30 can filter the airflow entering the dust cup 20. When the cleaning device 100 finishes vacuuming, the cup lid 22 can open the dust outlet 211 so that the dirt in the dust cup 20 can be discharged through the dust outlet 211.

[0046] Specifically, when the dust cup 22 is open and the dust outlet 211 is open, the motor pre-filter 32 can rotate relative to the main unit 10; when the dust cup 22 is closed and the dust outlet 211 is closed, the motor pre-filter 32 and the main unit 10 are stationary relative to each other. In other words, when cleaning the dirt in the dust cup 20, the motor pre-filter 32 can rotate relative to the main unit 10 so that it can be self-cleaned at the same time as cleaning the dirt in the dust cup 20.

[0047] For example, the filter device 30 may include a drive structure connected to the motor pre-filter 32 and opposite to the cup lid 22. When the cup lid 22 opens and closes the ash outlet 211, the drive structure slides in the vertical direction, driving the motor pre-filter 32 to slide in the vertical direction as well. The drive structure and the cup lid 22 may be detachably coupled. For example, when the cup lid 22 closes the ash outlet 211, it can stop the drive structure and restrict its rotation. At this time, the motor pre-filter 32 cannot rotate. When the cup lid 22 opens the ash outlet 211, the drive structure loses the stopping effect of the cup lid 22, and the motor pre-filter 32 moves downward under the action of gravity and can rotate synchronously with the motor pre-filter 32.

[0048] Combination Figure 2 In some embodiments of this utility model, the separation mechanism 31 has a receiving cavity 311 for accommodating the motor pre-filter 32. At least a portion of the motor pre-filter 32 is disposed in the receiving cavity 311, making the structure of the filtering device 30 compact and facilitating the filtration of the airflow after being filtered by the separation mechanism 31 by the motor pre-filter 32. Specifically, the entire motor pre-filter 32 may be disposed in the receiving cavity 311; or, a portion of the motor pre-filter 32 may be disposed in the receiving cavity 311, and another portion may extend out of the receiving cavity 311.

[0049] Combination Figure 2The receiving cavity 311 has a dust discharge port 3111 at its bottom, and the separation mechanism 31 includes a first seal 312 for opening and closing the dust discharge port 3111. For example, when the motor pre-filter 32 rotates, the first seal 312 can open the dust discharge port 3111, allowing dust and dirt separated from the motor pre-filter 32 to be discharged through the dust discharge port 3111. When the cleaning device 100 is vacuuming, the first seal 312 can close the dust discharge port 3111 to prevent airflow in the dust cup 20 from entering the motor pre-filter 32 through the dust discharge port 3111 and affecting the filtration effect of the filter device 30.

[0050] For example, the separation mechanism 31 may include a first filter section 313 and a second filter section 314 located downstream of the first filter section 313. The first sealing member 312 may be provided on the first filter section 313. Specifically, the first filter section 313 may move in the vertical direction. When the cup lid 22 closes the ash discharge port 211, the cup lid 22 abuts against the first filter section 313, and the first filter section 313 moves upward, causing the first sealing member 312 to close the ash discharge port 3111. When the cup lid 22 opens the ash discharge port 211, the cup lid 22 releases its abutment against the first filter section 313, and the first filter section 313 moves downward, causing the first sealing member 312 to open the ash discharge port 3111.

[0051] Of course, the first sealing element 312 can also be provided in the second filter part 314. Specifically, the second filter part 314 can move in the up and down direction. When the cup cover 22 closes the ash discharge port 211, the cup cover 22 abuts against the second filter part 314, and the second filter part 314 moves upward, so that the first sealing element 312 closes the ash discharge port 3111. When the cup cover 22 opens the ash discharge port 211, the cup cover 22 releases its abutment against the second filter part 314, and the second filter part 314 moves downward, so that the first sealing element 312 opens the ash discharge port 3111.

[0052] When the cup lid 22 opens the ash discharge port 211, the first sealing member 312 simultaneously opens the ash discharge port 3111, so that the dust separated from the motor pre-filter 32 can be discharged from the ash discharge port 3111 and discharged to the outside of the dust cup 20 through the ash discharge port 211.

[0053] Combination Figures 2 to 4In some embodiments of this utility model, the separation mechanism 31 includes a first filter section 313 and a second filter section 314. The second filter section 314 is located downstream of the first filter section 313, and at least a portion of the second filter section 314 is located inside the first filter section 313. Specifically, after the dust-laden airflow enters the dust cup 20, it first passes through the first filter section 313 for filtration, and then through the second filter section 314 for filtration. The first filter section 313 can filter larger dust particles such as debris, hair, and other contaminants, while the second filter section 314 can filter smaller dust particles. For example, the host 10 may have an air inlet duct 12, through which airflow containing dirt and dust enters the dust cup 20. The filter device 30 filters the airflow. Larger dirt such as debris and hair are first filtered by the first filter section 313 and intercepted on the outside of the first filter section 313. The second filter section 314 filters the airflow after it has been filtered by the first filter section 313 again. Finally, it is filtered by the motor pre-filter 32. The filtered clean airflow flows to the suction motor 11, and the dust and other dirt are collected in the dust storage chamber of the dust cup 20.

[0054] The first filter section 313 is rotatably connected to the second filter section 314. It can be understood that when the dust-laden airflow enters the dust cup 20, a high-speed rotating airflow is formed within the dust cup 20. Hair and other filamentous materials easily become entangled on the outside of the first filter section 313, which can easily lead to blockage after prolonged use. The first filter section 313 rotates to allow the second filter section 314 to rotate, meaning the first filter section 313 can rotate, which can loosen the hair and other filamentous materials entangled on the surface of the first filter section 313, facilitating the separation of the hair and other filamentous materials from the first filter section 313.

[0055] For example, the first filter section 313 may include an annular filter screen for primary filtration of the dust-laden airflow entering the dust cup 20, and the second filter section 314 may include a multi-cone cyclone separator for secondary filtration of the dust-laden airflow entering the dust cup 20.

[0056] The first filter section 313 includes an annular filter screen and a rotating support. The rotating support is rotatably connected to the second filter section 314. The annular filter screen is connected to the rotating support. A secondary dust collection section is constructed inside the rotating support. The second filter section 314 includes a multi-cone cyclone separator and a support frame. The support frame is connected to the main unit 10, and the multi-cone cyclone separator is connected to the support frame. The multi-cone cyclone separator is located inside the annular filter screen and is positioned above the secondary dust collection section. The support frame is used to connect the filter device 30 to the main unit 10. Additionally, the support frame is used to fix and support the second filter section 314, improving its structural stability. The secondary dust collection section, constructed inside the rotating support, can collect the dust filtered by the second filter section 314, making the filter device 30 more compact.

[0057] In addition, the first filter section 313 is configured to be rotatable, and the first filter section 313 and the motor pre-filter 32 can rotate synchronously; or, the first filter section 313 and the motor pre-filter 32 can rotate relative to each other, which can be adjusted according to the structure of the cleaning equipment 100 and the usage scenario.

[0058] Combination Figure 2 and Figure 4 In some embodiments of this utility model, the filtering device 30 further includes a connecting rod 33. The first filtering part 313 and the motor pre-filter 32 are connected by the connecting rod 33. The connecting rod 33 is rotatably connected to the second filtering part 314. The first filtering part 313 and the motor pre-filter 32 are relatively stationary. Specifically, the position of the second filtering part 314 can be relatively fixed, and the first filtering part 313 and the motor pre-filter 32 can rotate synchronously. The first filtering part 313 and the motor pre-filter 32 are rotatably connected to the second filtering part 314 by the connecting rod 33, which improves the stability of the first filtering part 313 and the motor pre-filter 32 during rotation and simplifies the connection structure of the filtering device 30. Furthermore, the first filter section 313 and the motor pre-filter 32 are relatively stationary. During the rotation of the first filter section 313, the hair wrapped around the surface of the first filter section is loosened. During the rotation of the motor pre-filter 32, the dust and other dirt on the motor pre-filter 32 are cleaned by centrifugal ash removal. This achieves synchronous self-cleaning of the first filter section 313 and the motor pre-filter 32, improves the cleaning efficiency of the filter device 30, and makes the filter device 30 less prone to clogging.

[0059] For example, the second filter section 314 can be connected to the host 10. In other words, the relative position of the second filter section 314 and the host 10 is fixed, so that the second filter section 314 can stably support the rotation of the first filter section 313 and the motor pre-filter 32. The first filter section 313 and the motor pre-filter 32 are connected by a connecting rod 33. When either the first filter section 313 or the motor pre-filter 32 rotates, the other component can be driven to rotate synchronously.

[0060] The second filter section 314 has a first bearing 341 between it and the connecting rod 33, and the first filter section 313 has a second bearing 342 between it and the second filter section 314. This reduces the friction between the second filter section 314 and the connecting rod 33, and between the first filter section 313 and the second filter section 314, thereby improving the smoothness of rotation between the first filter section 313 and the motor pre-filter 32.

[0061] Combination Figure 4For example, the second filter section 314 may include a bushing 3142. The upper end of the connecting rod 33 is inserted into the motor pre-filter 32. The connecting rod 33 is housed in the bushing 3142 of the second filter section 314 and rotatably connected to the bushing 3142 of the second filter section 314. The lower end of the connecting rod 33 is fixedly connected to the first filter section 313. A first bearing 341 may be provided between the bushing 3142 and the connecting rod 33 to reduce friction between the connecting rod 33 and the second filter section 314. One end of the bushing 3142 is connected to a multi-cone cyclone separator, and the first filter section 313 is rotatably connected to the other end of the bushing 3142. A second bearing 342 may be provided between the other end of the bushing 3142 and the first filter section 313. Specifically, when the first filter section 313 rotates, it drives the connecting rod 33 to rotate, thereby driving the motor pre-filter 32 to rotate. The position of the second filter section 314 is fixed, which can stably support the rotation of the first filter section 313 and the motor pre-filter 32.

[0062] In some embodiments of this utility model, the filtering device 30 further includes a connecting assembly, through which the first filtering part 313 and the motor pre-filter 32 are rotatably connected, and the first filtering part 313 and the motor pre-filter 32 rotate relative to each other. Specifically, during the rotation of the first filtering part 313 and the motor pre-filter 32, there is relative rotation between the first filtering part 313 and the motor pre-filter 32; in other words, the first filtering part 313 and the motor pre-filter 32 rotate at different speeds.

[0063] For example, the first filter section 313 can be driven to rotate by the airflow entering the dust cup 20. The rotation of the first filter section 313 drives the connecting component to rotate, and through the connecting component, drives the motor pre-filter 32 to rotate. The rotational speed of the motor pre-filter 32 driven by the connecting component is greater than the rotational speed of the first filter section 313, so that the motor pre-filter 32 has a higher rotational speed. During the rotation, the motor pre-filter 32 effectively removes dust and other dirt attached to it by centrifugal slinging, improving the self-cleaning effect of the motor pre-filter 32. Alternatively, the first filter section 313 or the motor pre-filter can be driven to rotate by the driving component of the base station 200 or the cleaning device 100. The rotational speed of the first filter section 313 can be greater than the rotational speed of the motor pre-filter 32, which can be adjusted according to the usage scenario of the cleaning device 100.

[0064] For example, the connecting assembly may include a shaft and a sleeve, with the first filter section 313 connected to the sleeve and the motor pre-filter 32 connected to the shaft, the shaft and sleeve being rotatably connected; or, the connecting assembly may also be a planetary gear to achieve different speed ratios between the first filter section 313 and the motor pre-filter 32. Figure 2 and Figure 3In some embodiments of this utility model, the dust cup 20 includes a cup body 21 and a cup lid 22. The cup body 21 is provided with a dust outlet 211, and the cup lid 22 is used to open and close the dust outlet 211. When the cup lid 22 closes the dust outlet 211, the first filter part 313 and the second filter part 314 are relatively stationary. When the cup lid 22 opens the dust outlet 211, the first filter part 313 can rotate relative to the second filter part 314. Specifically, when the cup lid 22 closes the ash outlet 211, the first filter section 313 and the second filter section 314 are relatively stationary. That is to say, the first filter section 313 cannot rotate, which facilitates the cooperation of the first filter section 313 and the second filter section 314 to perform two-stage filtration of the dirty air entering the dust cup 20, thereby improving the filtration effect and stability of the separation mechanism 31. When the cup lid 22 opens the ash outlet 211, the first filter section 313 can rotate, which facilitates the loosening of hair wrapped around the surface of the first filter section 313, making it easier for hair and other filamentous materials to be separated from the first filter section 313. The separated dirt can be discharged to the outside of the cleaning equipment 100 through the ash outlet 211.

[0065] For example, the second filter section 314 may have a first position and a second position arranged in a vertical direction. When the cup lid 22 closes the ash outlet 211, the second filter section 314 moves upward to the first position and locks the first filter section 313. When the cup lid 22 opens the ash outlet 211, the second filter section 314 moves downward to the second position and releases the lock on the first filter section 313, allowing the first filter section 313 to rotate. Alternatively, the first filter section 313 may have a third position and a fourth position arranged in a vertical direction. When the cup lid 22 closes the ash outlet 211, the first filter section 313 moves upward to the third position, and the cup lid 22 abuts against the first filter section 313 and restricts its rotation. When the cup lid 22 opens the ash outlet 211, the cup lid 22 releases the restriction on the rotation of the first filter section 313, and the first filter section 313 moves downward to the fourth position, becoming rotatable relative to the second filter section 314.

[0066] In some embodiments of this utility model, the cup lid 22 is provided with a damping member 221. When the cup lid 22 closes the ash outlet 211, the damping member 221 abuts against the first filter part 313 and restricts the rotation of the first filter part 313; when the cup lid 22 opens the ash outlet 211, the damping member 221 releases the restriction on the rotation of the first filter part 313. Specifically, the damping member 221 can be connected to the side of the cup lid 22 facing the cup body 21. When the cup lid 22 closes the ash outlet 211, the damping member 221 presses the first filter part 313 upward, preventing the first filter part 313 from rotating, thereby enabling the filter device 30 to filter the dust-laden airflow entering the dust cup 20 and preventing the rotation of the first filter part 313 from affecting the filtration effect of the filter device 30. Exemplarily, the damping member 221 can be a rubber part.

[0067] Combination Figure 2and 4 In some embodiments of the present invention, the second filter section 314 has a receiving cavity 311 for accommodating the motor pre-filter 32. At least a portion of the motor pre-filter 32 is disposed in the receiving cavity 311, making the structure of the filter device 30 more compact and facilitating the filtration of the airflow after being filtered by the second filter section 314 by the motor pre-filter 32.

[0068] The receiving cavity 311 has a dust discharge port 3111 at its bottom. The separation mechanism 31 includes a first sealing element 312, which is located on the first filter section 313. When the cup lid 22 closes the dust discharge port 211, the first sealing element 312 closes the dust discharge port 3111; when the cup lid 22 opens the dust discharge port 211, the first sealing element 312 opens the dust discharge port 3111. In conjunction with the foregoing, the first filter section 313 and the motor pre-filter 32 are relatively stationary. When the cup lid 22 opens the dust discharge port 211, the first filter section 313 can rotate. That is, the first filter section 313 and the motor pre-filter 32 can rotate synchronously to facilitate simultaneous cleaning of the first filter section 313 and the motor pre-filter 32. At this time, the first sealing element 312 can open the dust discharge port 3111, and the dust and dirt separated from the motor pre-filter 32 can be discharged into the dust cup 20 through the dust discharge port 3111 and then discharged to the outside of the cleaning equipment 100 through the dust discharge port 211.

[0069] In addition, when the cup lid 22 closes the ash discharge port 211, it facilitates the cleaning equipment 100 to close the ash discharge port 3111 through the first seal 312 during dust collection, preventing dust in the dust cup 20 from entering the motor pre-filter 32 through the ash discharge port 3111 and affecting the filtration effect of the filter device 30.

[0070] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the host 10 has an air inlet duct 12 connected to the dust cup 20 and a self-cleaning duct 13 connected to the base station 200. The cleaning device 100 also includes an air duct switching component 14, which is disposed on the host 10 and is used to change the airflow direction within the cleaning device 100. Exemplarily, one end of the air inlet duct 12 can be connected to the suction head of the cleaning device 100, and the other end is connected to the dust cup 20. When the cleaning device 100 is vacuuming, the suction motor 11 works, and the suction head sucks dust, hair, debris and other dirt from the working surface into the dust cup 20 through the air inlet duct 12. The filter device 30 filters the airflow, and the clean airflow filtered by the filter device 30 is discharged outside the cleaning device 100 through the suction motor 11.

[0071] The cleaning equipment 100 has a working mode and a self-cleaning mode. In the working mode, the air duct switching component 14 connects the suction motor 11 and the dust cup 20; in the self-cleaning mode, the air duct switching component 14 connects the suction motor 11 and the self-cleaning air duct 13.

[0072] Specifically, in the working mode, the air duct switching component 14 connects the suction motor 11 to the dust cup 20. Figure 2 The middle arrow indicates the airflow direction. Dust, hair, debris, and other contaminants from the work surface are drawn into the dust cup 20 through the air inlet duct 12. The filter device 30 filters the airflow, and the clean airflow after filtration by the filter device 30 is discharged outside the cleaning equipment 100 via the suction motor 11. Combined with... Figure 5 After the cleaning device 100 completes the cleaning work, it can be connected to the base station 200. In the self-cleaning mode, the air duct switching component 14 connects the suction motor 11 to the self-cleaning air duct 13. The dust cup 20 can be connected to the base station 200, and the base station 200 is connected to the self-cleaning air duct 13. Under the action of the suction motor 11, a negative pressure is generated in the base station 200, so that the dust, debris, hair and other dirt in the dust cup 20 are collected in the base station 200. The airflow in the base station 200 flows back to the suction motor 11 through the self-cleaning air duct 13 and is discharged to the outside of the cleaning device 100 through the suction motor 11. By setting a self-cleaning air duct 13 and an air duct switching component 14 on the cleaning device 100, the base station 200 does not need to be equipped with a motor. By using the suction motor 11 of the cleaning device 100 to introduce negative pressure into the base station 200, a negative pressure is generated inside the base station 200. The negative pressure inside the base station 200 can clean the dust cup 20 of the cleaning device 100, simplifying the structure of the base station 200 and reducing the noise of the base station 200 during operation.

[0073] Exemplarily, the air duct switching assembly 14 includes a switching body and a sealing switching element. The switching body has a first interface communicating with the dust cup 20, a second interface communicating with the self-cleaning air duct 13, and a third interface communicating with the suction motor 11. The sealing switching element is movable to selectively block the first and second interfaces, thereby controlling the suction motor 11 to selectively communicate with the dust cup 20 and the self-cleaning air duct 13. Exemplarily, when the cleaning device 100 is in working mode, the sealing switching element blocks the second interface to control the suction motor 11 to communicate with the dust cup 20. When the cleaning device 100 is in self-cleaning mode, the sealing switching element blocks the first interface to control the suction motor 11 to communicate with the self-cleaning air duct 13. By setting the switching body and the sealing switching element to cooperate, the structure of the air duct switching assembly 14 is simplified, making it easier for the cleaning device 100 to switch the air duct in different modes.

[0074] Furthermore, in self-cleaning mode, airflow flows along the air inlet duct 12, dust cup 20, base station 200, self-cleaning duct 13, and suction motor 11, driving the first filter section 313 to rotate. That is, the airflow entering the dust cup 20 in self-cleaning mode can drive the first filter section 313 to rotate. Specifically, in operating mode, when dust-laden airflow enters the dust cup 20 through the air inlet duct 12, a high-speed rotating airflow is formed within the dust cup 20. Hair and other filamentous materials easily become entangled on the outside of the first filter section 313. However, when the cleaning device 100 is in self-cleaning mode, the airflow entering the dust cup 20 through the air inlet duct 12 can drive the first filter section 313 to rotate, allowing the hair and other filamentous materials entangled in the first filter section 313 in operating mode to be loosened and more easily dislodged. The first filter section 313 is driven by the airflow entering the dust cup 20. Therefore, its rotation direction is the same as the rotation direction of the airflow entering the dust cup 20, and also the same as the direction in which the hair driven by the airflow rotates and wraps around. Compared with the case where the first filter section 313 does not rotate, when the airflow rotates a certain number of times in the dust cup 20, the first filter section 313 rotates less, that is, the number of times the hair wraps around is also lower. Therefore, it is more conducive to the separation of hair from the first filter section 313. In the self-cleaning mode, the cleaning device 100 can improve the cleaning effect on the filter device 30 without the need to set up a separate structure for cleaning the filter device 30, thereby reducing the situation where hair wrapping around and clogging the first filter section 313 affects the filtration efficiency.

[0075] In conjunction with the foregoing, the first filter section 313 and the motor pre-filter 32 are relatively stationary. That is to say, during the rotation of the first filter section 313, the motor pre-filter 32 can be driven to rotate synchronously, so that the cleaning device 100 can simultaneously achieve self-cleaning of the first filter section 313 and the motor pre-filter 32 in the self-cleaning mode, thereby improving the self-cleaning effect of the filter device 30.

[0076] Combination Figure 2 and Figure 4In some embodiments of this utility model, the main unit 10 has a suction port 15, which is connected to the suction motor 11. A second seal 321 is provided between the suction port 15 and the motor pre-filter 32. The cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the suction port 15 is connected to the motor pre-filter 32, and the second seal 321 seals the gap between the motor pre-filter 32 and the suction port 15 and restricts the rotation of the motor pre-filter 32. In the self-cleaning mode, the second seal 321 releases the restriction on the rotation of the motor pre-filter 32. Specifically, in operating mode, the airflow is filtered by the separation mechanism 31 and then by the motor pre-filter 32. The filtered clean airflow is then discharged to the outside of the cleaning equipment 100 by the suction motor 11. The second seal 321 prevents air leakage between the motor pre-filter 32 and the suction port 15, which would otherwise cause some airflow to enter the suction port 15 directly without being filtered by the motor pre-filter 32, affecting the service life of the motor. Simultaneously, the second seal 321 also restricts the rotation of the motor pre-filter 32, facilitating stable airflow filtration. In self-cleaning mode, the second seal 321 restricts the rotation of the pre-filter, allowing the motor pre-filter 32 to self-clean during rotation. The second filter element can be an elastic rubber component, and it can be fitted onto the end of the pre-filter near the suction port 15.

[0077] For example, the upper end of the motor pre-filter 32 is connected to the suction port 15 through the second seal 321, and the lower end of the motor pre-filter 32 is connected to the first filter part 313 through the connecting rod 33, and is rotatably connected to the second filter part 314 through the bearing. The second filter part 314 is provided with a receiving cavity 311 for accommodating the motor pre-filter 32 in the middle. The bottom of the receiving cavity 311 is provided with a dust discharge port 3111 for the motor pre-filter 32, which is opened or sealed by the first seal 312 provided in the first filter part 313. In the working mode of the cleaning equipment 100, the second seal 321 abuts against the suction port 15 to prevent air leakage between the motor pre-filter 32 and the suction port 15 when the suction motor 11 is working. At the same time, the first filter part 313 is stopped from rotating by the cup cover 22, so the motor pre-filter 32 does not rotate. In the self-cleaning mode, the cup cover 22 opens the ash discharge port 211, the first filter part 313 drives the motor pre-filter 32 to move downward, the second seal 321 disengages from the suction port 15, and the first seal 312 on the first filter part 313 opens the ash discharge port 3111. At this time, the motor pre-filter 32 can rotate under the rotation of the first filter part 313, realizing the self-cleaning of the motor pre-filter 32 and the first filter part 313.

[0078] Combination Figure 5The present invention also proposes a cleaning system, including a base station 200 and the aforementioned cleaning device 100, wherein the cleaning device 100 and the base station 200 are detachably connected.

[0079] Furthermore, the base station 200 has a dust collection duct 210 and a bypass duct 220 that are interconnected, and the cleaning device 100 has an air inlet duct 12 and a self-cleaning duct 13. The cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the air inlet duct 12 is fluidly connected to the dust cup 20, and the suction motor 11 is fluidly connected to the filter device 30. In the self-cleaning mode, the air inlet duct 12 is fluidly connected to the dust cup 20, and the dust cup 20 is fluidly connected to the dust collection duct 210, and the bypass duct 220 is fluidly connected to the self-cleaning duct 13, which is fluidly connected to the suction motor 11.

[0080] The cleaning equipment 100 may include an air duct switching component 14. After the cleaning equipment 100 is connected to the base station 200, the air duct switching component 14 can be triggered by the base station 200 to switch the air duct.

[0081] For example, in the working mode, dust, hair, debris, and other contaminants from the working surface of the cleaning device 100 are drawn into the dust cup 20 through the air inlet duct 12. The filter device 30 filters the airflow, and the clean airflow after dust filtration is discharged outside the cleaning device 100 via the suction motor 11. In the self-cleaning mode, the base station 200 does not require an additional motor. After the cleaning device 100 is connected to the base station 200, one end of the self-cleaning duct 13 can be fluidly connected to the suction motor 11, and the other end of the self-cleaning duct 13 is connected to the bypass ventilation duct 220 of the base station 200. When the suction motor 11 operates, it creates a negative pressure on the dust cup 20 from the dust bag of the base station 200, thereby cleaning the contaminants in the dust cup 20. At this time, the airflow direction is: outside atmosphere - air inlet duct 12 - dust cup 20 - dust collection duct 210 - bypass ventilation duct 220 - self-cleaning duct 13 - duct switching component 14 - suction motor 11 - outside atmosphere.
