[0003] The present invention relates to the technical field of cleaning tools, and particularly to a cleaning equipment and a cleaning system. Background art

[0004] Cleaning equipment usually includes a filter, a suction head, a suction device and a dust cup, etc. The external dirt is sucked in through the suction head and introduced into the dust cup, and filtered by the filter, so that the dirt can be retained in the dust cup, while the filtered clean air flow can flow out of the filter to enter the suction device and be discharged from the cleaning equipment, forming an air flow cycle for the cleaning equipment to clean.

[0005] When the cleaning equipment is cleaning, the dirty air sucked in by the suction head enters the dust cup through the air inlet on the dust cup and rotates around the cylindrical filter. When the cleaning equipment sucks in some long hairs, due to the principle of the cyclone separator, the air flow drives the hairs to rotate around the filter. After long - term use, the long hairs will wind around the surface of the filter, causing the filter to be blocked and affecting the efficiency of dust suction and filtration.

Detailed implementation manners

[0045] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the 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 drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0046] When the cleaning device is cleaning, the dirty air sucked in by the suction head enters the dust cup through the air inlet on the dust cup and rotates around the filter. When the cleaning device sucks in some long hairs, based on the principle of the cyclone separator, the airflow drives the hairs to rotate around the filter. After long-term use, the long hairs will wind around the surface of the filter, causing the filter to be blocked and affecting the suction filtration efficiency. In order to remove the hairs wound on the surface of the cyclone separator, it is necessary to additionally set a cleaning mechanism, which results in a complex overall structure, increases the weight of the whole machine, affects the user experience, and at the same time, the cleaning mechanism needs to extend from the main machine into the dust cup, which may have problems in terms of sealing, and the complex structure is prone to failure and also increases the cost. Based on this, the present invention proposes a cleaning device, which can facilitate the cleaning of the dirt wound on the surface of the filter device by improving the structure of the filter device.

[0047] Combined Figure 1 According to an embodiment of the present invention, the cleaning device 100 includes a dust cup 10 and a filtering device 20. At least a part of the filtering device 20 is disposed in the dust cup 10. Exemplarily, a dust storage cavity may be provided in the dust cup 10. When the user uses the cleaning device 100 to clean the working surface, the filtering device 20 can be used to separate and filter the dirty air entering the dust storage cavity. The clean air flow filtered by the filtering device 20 flows through the air outlet of the dust cup 10 to the suction device of the cleaning device 100, and the filtered dust impurities are collected in the dust storage cavity.

[0048] Combined Figure 1 and Figure 3 The filtering device 20 includes a support portion 21 and a first filtering portion 22, and the first filtering portion 22 is rotatably connected to the support portion 21. Among them, the position of the support portion 21 can be relatively fixed. Exemplarily, the support portion 21 can be connected to the dust cup 10; or, the support portion 21 can be connected to the main body of the cleaning device 100; or, the support portion 21 can be connected to both the dust cup 10 and the main body of the cleaning device 100. The position of the support portion 21 is relatively fixed, which is convenient for stably supporting the rotation of the first filtering portion 22 through the support portion 21.

[0049] Combined Figure 1 and Figure 5 The filtering device 20 further includes a second filtering portion 23, and at least a part of the second filtering portion 23 is disposed inside the first filtering portion 22. Specifically, the first filtering portion 22 is disposed on the outside. The first filtering portion 22 can perform primary filtering on larger dust particles such as debris and hair, and the second filtering portion 23 can perform secondary filtering on smaller dust particles and the like. Exemplarily, the dust cup 10 may have an air inlet 112. The air flow containing dirt and dust enters the dust storage cavity from the air inlet 112. The filtering device 20 filters the air flow. Larger dirt such as debris and hair is first filtered by the first filtering portion 22 and intercepted on the outside of the first filtering portion 22. The second filtering portion 23 performs secondary filtering on the air flow filtered by the first filtering portion 22. The filtered clean air flow flows through the air outlet of the dust cup 10 to the suction device of the cleaning device 100, and dirt such as dust is collected in the dust storage cavity. It can be understood that when the cleaning device 100 is in the working state, when the dust-containing air flow enters the dust cup 10, a high-speed rotating air flow is formed in the dust cup 10. Filamentous substances such as hair are easily wound around the outside of the first filtering portion 22, and the first filtering portion 22 is likely to be blocked after long-term use. The first filtering portion 22 is rotatably connected to the support portion 21, which can facilitate the loosening of the filamentous substances such as hair wound on the surface of the first filtering portion 22, facilitate the separation of the filamentous substances such as hair from the first filtering portion 22, and facilitate the cleaning of the filtering device 20.

[0050] Among them, the second filtering part 23 is slidably connected to the supporting part 21 in the up-and-down direction, and the sliding direction of the second filtering part 23 is parallel to the axial direction of the first filtering part 22. Combining Figure 1 and Figure 2 , the axis of the first filtering part 21 is A, and the supporting part 21 can improve the stability of the second filtering part 23 during the sliding process. Exemplarily, the second filtering part 23 may have different positions when sliding along the axial direction. Combining Figure 1 , the second filtering part 23 may have a first position. In the first position, the second filtering part 23 cooperates with the first filtering part 22 to filter the dust entering the dust cup 10. Combining Figure 2 , the second filtering part 23 may also have a second position. In the second position, the second filtering part 23 is spaced apart from the first filtering part 22 in the radial direction, which is convenient for the first filtering part 22 to rotate to loosen the hair and other dirt wound on its surface. Of course, the second filtering part 23 of the present invention may also have other positions. Exemplarily, when the second filtering part 23 moves downward, it is convenient to clean the second filtering part 23 to prevent dust from accumulating in the second filtering part 23 after long-term use, which affects the cleaning efficiency of the cleaning device 100.

[0051] According to the cleaning device 100 of the embodiment of the present invention, the supporting part 21 supports the first filtering part 22 and the second filtering part 23, improves the structural stability of the first filtering part 22 and the second filtering part 23, and the first filtering part 22 can rotate, which is convenient for loosening the filaments wound on the surface of the first filtering part 22, facilitating the separation of the filaments from the first filtering part 22, and facilitating the cleaning of the filtering device 20.

[0052] It should be noted that in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "up", "down", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0053] Among them, at least a part of the filtering device 20 is disposed in the dust cup 10. Exemplarily, all of the filtering device 20 can be disposed in the dust cup 10; or, a part of the filtering device 20 is disposed in the dust cup 10. Among them, the filtering device 20 can be connected to the dust cup 10. That is to say, when the dust cup 10 is separated from the main body of the cleaning device 100, the filtering device 20 can be separated from the main body of the cleaning device 100 together with the dust cup 10; or, the filtering device 20 can be connected to the main body of the cleaning device 100, and the dust cup 10 is detachably connected to the main body of the cleaning device 100. After the dust cup 10 is installed on the main body of the cleaning device 100, at least a part of the filtering device 20 extends into the dust cup 10, so that the filtering device 20 can filter the dust and dirt inhaled into the dust cup 10. When the dust cup 10 is separated from the main body of the cleaning device 100, the filtering device 20 is still connected to the main body of the cleaning device 100. When the dust cup 10 needs to be replaced or cleaned, the disassembly of the dust cup 10 is more convenient. Since the filtering device 20 is connected to the main body of the cleaning device 100, the disassembly and assembly of the dust cup 10 do not affect the filtering device 20, improving the efficiency of the disassembly and assembly of the dust cup 10.

[0054] In the foregoing embodiment where the filtering device 20 is connected to the main body of the cleaning device 100, the filtering device 20 and the main body of the cleaning device 100 can be detachably connected to facilitate the replacement or maintenance of the filtering device 20.

[0055] In the present invention, the cleaning device 100 can be a vacuum cleaner, a floor sweeping robot, a mite remover, a floor washer, etc.

[0056] Exemplarily, the first filtering part 22 can include a filter screen, a sponge, etc., to perform primary filtering on the dirt entering the dust cup 10. At least a part of the second filtering part 23 is disposed inside the first filtering part 22. Specifically, all of the second filtering part 23 can be disposed inside the first filtering part 22, or a part of the second filtering part 23 is disposed inside the first filtering part 22, and the other part extends out of the first filtering part 22. The second filtering part 23 can include a HEPA filter or a multi-cone cyclone separator, etc. The second filtering part 23 is located downstream of the first filtering part 22 and can perform secondary filtering on the airflow filtered by the first filtering part 22.

[0057] Combined Figure 1 and Figure 2, in some embodiments of the present invention, the dust cup 10 includes a cup body 11 and a cup lid 12. The cup body 11 has a dust discharge port 111, and the cup lid 12 is used to open and close the dust discharge port 111. Specifically, a dust storage cavity may be provided in the dust cup 10. During the operation of the cleaning device 100, the cup lid 12 closes the dust discharge port 111, and dust, dirt, etc. are collected in the dust storage cavity. When it is necessary to clean the dust cup 10, the cup lid 12 opens the dust discharge port 111 to clean the dirt in the dust storage cavity. Exemplarily, the user can manually open the cup lid 12 to clean the dust cup 10, or the cleaning device 100 can be docked with the base station 200 to clean the dirt in the dust cup 10 through the base station 200.

[0058] Combined with Figure 1 and Figure 2 , the cleaning device 100 further includes a driving member 24. The driving member 24 is connected to the second filtering part 23 and is opposite to the cup lid 12. When the cup lid 12 opens and closes the dust discharge port 111, the driving member 24 is driven to slide in the up and down direction, and drives the second filtering part 23 to slide in the up and down direction. Specifically, the driving member 24 is connected to the second filtering part 23, and the driving member 24 can drive the second filtering part 23 to slide in the up and down direction. In addition, the switching of the on / off state of the cup lid 12 causes the driving member 24 to drive the second filtering part 23 to move up and down, facilitating the movement of the second filtering part 23 in the up and down direction.

[0059] Among them, the driving member 24 and the cup lid 12 can be detachably engaged. Exemplarily, when the cup lid 12 is in the closed state, the cup lid 12 can abut against the driving member 24. When the cup lid 12 opens the dust discharge port 111, the driving member 24 loses the abutting action of the cup lid 12, and the second filtering part 23 moves downward under the action of gravity, simplifying the structure of the driving member 24; or, a transmission part may be connected between the cup lid 12 and the driving member 24. One end of the transmission part is drivingly connected to the driving member 24, and the other end is rotatably connected to the cup lid 12. When the cup lid 12 opens and closes, the transmission part converts the rotation of the cup lid 12 into the up and down movement of the driving member 24. When the cup lid 12 opens the dust discharge port 111, the transmission part drives the driving member 24 to move downward. When the cup lid 12 closes the dust discharge port 111, the transmission part drives the driving member 24 to move upward, so that the driving member 24 can stably drive the second filtering part 23 to move up and down.

[0060] Exemplarily, when the cup lid 12 opens the ash discharge port 111, the driving member 24 drives the second filtering portion 23 to move downward. The second filtering portion 23 and the first filtering portion 22 can be spaced apart in the radial direction, facilitating the rotation of the first filtering portion 22 to loosen the dirt wound on the surface of the first filtering portion 22. Additionally, the second filtering portion 23 and the first filtering portion 22 being spaced apart in the radial direction can prevent the rotation of the first filtering portion 22 from affecting the second filtering portion 23. When the cup lid 12 closes the ash discharge port 111, the driving member 24 drives the second filtering portion 23 to move upward, and the first filtering portion 22 and the second filtering portion 23 cooperate to filter the dust entering the dust cup 10.

[0061] Combined with Figure 1 and Figure 2 In some embodiments of the present invention, when the cup lid 12 opens the ash discharge port 111, the cup lid 12 releases the driving member 24, and the second filtering portion 23 moves downward; when the cup lid 12 closes the ash discharge port 111, the cup lid 12 abuts against the driving member 24, and the driving member 24 drives the second filtering portion 23 to move upward. Specifically, when the cup lid 12 is closed, the driving member 24 drives the secondary filter to move upward under the abutting action of the cup lid 12. When the cup lid 12 is opened, the driving member 24 loses the abutting action of the dust cup 10 lid, and under the action of gravity, the secondary filter moves downward, making the structure of the driving member 24 simple and facilitating the switching of the open and closed states of the cup lid 12 to drive the second filtering portion 23 to move up and down.

[0062] Exemplarily, the driving member 24 may include a push rod 241. One end of the push rod 241 is connected to the second filtering portion 23, and the other end extends toward the direction of the ash discharge port 111 and is detachably docked with the cup lid 12. When the cup lid 12 closes the ash discharge port 111, the other end of the push rod 241 can abut against the cup lid 12. When the cup lid 12 opens the ash discharge port 111, the push rod 241 is separated from the cup lid 12 and loses the abutting action of the dust cup 10 lid, and the second filtering portion 23 moves downward under the action of gravity. By providing the push rod 241, the structure of the driving member 24 is simplified, the failure rate of the cleaning device 100 is reduced, and it is convenient for the driving member 24 to stably drive the second filtering portion 23 to move up and down.

[0063] Combined with Figure 5 and Figure 6 In some embodiments of the present invention, the driving member 24 is provided in the filtering device 20. The driving member 24 includes a push rod 241. The push rod 241 is movably disposed inside the support portion 21 in the up and down direction. The support portion 21 can guide the movement of the push rod 241, improving the structural stability of the push rod 241 and the stability during the up and down movement, and thus stably driving the second filtering portion 23 to move in the up and down direction.

[0064] Combined with Figure 5 and Figure 6In some embodiments of the present invention, the support portion 21 includes an upper bracket 211 and a lower bracket 212, the upper bracket 211 is fixedly connected to the lower bracket 212, and a sliding range of the second filter portion 23 is defined between the upper bracket 211 and the lower bracket 212. The upper bracket 211 and the lower bracket 212 cooperate to limit the stroke of the second filter portion 23. For example, when the cup cover 12 closes the ash discharge port 111, the second filter portion 23 can move upward to the first position, so that the first filter portion 22 and the second filter portion 23 cooperate to filter the dirt entering the dust cup 10. When the cup cover 12 opens the ash discharge port 111, the second filter portion 23 moves downward to the second position. At this time, the first filter portion 22 can rotate around the axis direction to loosen the hair entangled on the surface of the first filter portion 22. By setting the upper bracket 211 and the lower bracket 212 to define the sliding range of the second filter portion 23, the second filter portion 23 can be stably moved between the first position and the second position, thereby improving the working stability of the cleaning device 100.

[0065] Exemplarily, when the cup cover 12 closes the ash discharge port 111, the second filter part 23 abuts against the upper bracket 211, and when the cup cover 12 opens the ash discharge port 111, the second filter part 23 abuts against the lower bracket 212. The upper bracket 211 can limit the second filter part 23 when it moves upward, and the lower bracket 212 can limit the second filter part 23 when it moves downward, thereby improving the sliding stability of the second filter part 23.

[0066] Combination Figure 7 Optionally, the second filter part 23 includes a multi-cone cone 233 and a lower cover plate 235, the lower cover plate 235 is connected to the lower end of the multi-cone cone 233, when the cup cover 12 is in the open state, the lower cover plate 235 abuts against the lower bracket 212, and the lower cover plate 235 and the lower bracket 212 cooperate to limit the second filter part 23 to prevent the second filter part 23 from being separated from the second position. Exemplarily, a plate body 2351 of the lower cover plate 235 may be provided with a plurality of through holes 2352 penetrating the plate body 2351, and the dust outlet end of the multi-cone cone 233 may be penetrated through the through holes 2352.

[0067] In addition, the upper bracket 211 and the lower bracket 212 are fixedly connected and used to support the first filter part 22 and the second filter part 23, wherein the upper bracket 211 can be connected to the main body of the cleaning device 100, and the lower bracket 212 can be rotatably connected to the first filter part 22. The dust cup 10 is detachably connected to the main body of the cleaning device 100. After the dust cup 10 is removed, the filter device 20 can still be connected to the main body of the cleaning device 100, which is convenient for replacing and cleaning the dust cup 10, and when the dust cup 10 is removed, the filter device 20 will not be affected.

[0068] Combination Figure 6, in some embodiments of the present invention, at least one of the upper bracket 211 and the lower bracket 212 includes a connecting column, the connecting column extends along the axial direction, the second filtering part 23 has a sliding groove 231 extending along the axial direction, and the second filtering part 23 is slidably connected to the connecting column through the sliding groove 231. Specifically, the upper bracket 211 may include a connecting column; or, the lower bracket 212 includes a connecting column; or, both the upper bracket 211 and the lower bracket 212 include connecting columns. By setting the cooperation between the connecting column and the sliding groove 231, the second filtering part 23 can be guided, facilitating the second filtering part 23 to stably slide along the axial direction, and further enabling the second filtering part 23 to stably lock and release the first filtering part 22, improving the working stability of the cleaning device 100.

[0069] Wherein, the connecting column can pass through the sliding groove 225 to facilitate the stable support of the second filtering part 22 to slide along the axial direction by the connecting column.

[0070] Combined with Figure 6 , in some embodiments of the present invention, the connecting column includes a first connecting column 2111 provided on the upper bracket 211 and a second connecting column 2121 provided on the lower bracket 212, and the first connecting column 2111 and the second connecting column 2121 are fixedly connected. The upper bracket 211 and the lower bracket 212 are fixedly connected through the first connecting column 2111 and the second connecting column 2121, which is convenient for the installation of the filtering device 20 and improves the structural stability of the support part 21. After the upper bracket 211 and the lower bracket 212 are connected, the second filtering part 23 can be stably supported to slide along the axial direction.

[0071] Wherein, the first connecting column 2111 may include three arranged uniformly along the circumferential direction, the second connecting column 2121 may include three arranged uniformly along the circumferential direction, and the sliding groove 231 includes three arranged uniformly along the circumferential direction. On the one hand, the first connecting column 2111 and the second connecting column 2121 are connected, making the connection between the upper bracket 211 and the lower bracket 212 more stable. On the other hand, the problem of eccentricity of the second filtering part 23 during the up and down sliding process can be effectively avoided.

[0072] Exemplarily, the first connecting column 2111 and the second connecting column 2121 can be fixed by fixing parts such as screws. A positioning groove can be provided at the end of the first connecting column 2111, and the second connecting column 2121 can be inserted into the positioning groove, which can pre-position the installation of the upper bracket 211 and the lower bracket 212 and improve the stability after the upper bracket 211 and the lower bracket 212 are connected.

[0073] Combined with Figure 7 and Figure 8, optionally, the second filtering part 23 includes a multi-cone body 233, an upper cover plate 234 and a lower cover plate 235. The upper cover plate 234 is connected to the upper end of the multi-cone body 233, and the lower cover plate 235 is connected to the lower end of the multi-cone body 233. The upper support 211 and the lower support 212 define a sliding range of the second filtering part 23. Exemplarily, the upper support 211 and the lower support 212 can limit the sliding of the second filtering part 23 between a first position and a second position. When the second filtering part 23 slides upward to the first position, the upper cover plate 234 can abut against the upper support 211. When the second filtering part 23 slides downward to the second position, the lower cover plate 235 abuts against the lower support 212. The cooperation between the upper cover plate 234 and the upper support 211, and the cooperation between the lower cover plate 235 and the lower support 212 can stably limit the movement of the second filtering part 23 between the first position and the second position.

[0074] Among them, the aforementioned sliding groove 231 can be arranged on the upper cover plate 234 and / or the lower cover plate 235. Exemplarily, a first sleeve 2342 can be arranged on the side of the upper cover plate 234 facing the lower cover plate 235, and a second sleeve 2353 can be arranged on the side of the lower cover plate 235 facing the upper cover plate 234. The first sleeve 2342 and the second sleeve 2353 are connected and configured to form the sliding groove 231, and at least a part of the connecting column can be slidably arranged in the sliding groove 231.

[0075] In addition, the filtering device 20 can include a driving member 24. The upper end of the driving member 24 can be connected to the upper cover plate 234 and the lower cover plate 235. That is to say, the upper end of the driving member 24 is connected to the second filtering part 23 through the upper cover plate 234 and the lower cover plate 235. The lower end of the driving member 24 can be detachably cooperated with the cup cover 12. When the cup cover 12 is closed, the driving member 24 drives the second filtering part 23 to move upward under the abutting action of the cup cover 12. When the cup cover 12 is opened, the driving member 24 loses the abutting action of the cup cover 12, and the second filtering part 23 moves downward under the action of gravity. The driving member 24 is connected to the upper cover plate 234 and the lower cover plate 235, which is convenient for the driving member 24 to stably drive the second filtering part 23 to move up and down, and improves the movement stability of the second filtering part 23. Exemplarily, the driving member 24 can include a push rod 241.

[0076] Combined with Figure 4 and Figure 8 , in some embodiments of the present invention, the support part 21 includes a support column 2122. The support column 2122 and the second filtering part 23 are arranged oppositely in the up and down direction. The first filtering part 22 is rotatably connected to the support column 2122. The support column 2122 is arranged below the second filtering part 23, so as to utilize the space below the second filtering part 23 to support the rotation of the first filtering part 22, improve the structural stability of the first filtering part 22, and make the structure of the filtering device 20 compact.

[0077] Combined with Figures 3 to 6, in some embodiments of the present invention, the support part 21 includes an upper bracket 211 and a lower bracket 212. The upper bracket 211 is fixedly connected to the lower bracket 212. The support column 2122 is provided on the lower bracket 212. A sliding interval of the second filter part 23 is defined between the upper bracket 211 and the lower bracket 212. The upper bracket 211 and the lower bracket 212 cooperate to limit the stroke of the second filter part 23. The first filter part 22 is rotatably connected to the lower bracket 212, and the support column 2122 is arranged below the second filter part 23, making the overall structure of the filter device 20 more compact, and facilitating the cooperation of the upper bracket 211 and the lower bracket 212 to support the rotation of the first filter part 22 and the up-and-down sliding of the second filter part 23, improving the movement stability of the first filter part 22 and the second filter part 23.

[0078] Combined with Figure 4 , in some embodiments of the present invention, the first filter part 22 includes a filter screen main body 221 and a rotating support member 222. The rotating support member 222 is rotatably connected to the support column 2122. Specifically, the filter screen main body 221 is mainly used to filter the dirt entering the dust cup 10. The rotating support member 222 supports the filter screen main body 221 and cooperates with the support column 2122 to enable the first filter part 22 to rotate around the axis to loosen the hair wound on the surface of the filter screen main body 221.

[0079] Exemplarily, the filter screen main body 221 may include a filter net 2211 and a filter screen bracket 2212. The filter screen bracket 2212 surrounds the axis of the first filter part 22 and has a hollow structure. The filter net 2211 is arranged on the filter screen bracket 2212 and covers the hollow structure.

[0080] Combined with Figure 8 and Figure 9 , further, the rotating support member 222 includes a support main body 2221. The support main body 2221 is connected to the lower end of the filter screen main body 221. A secondary dust accumulation cavity 2223 communicating with the second filter part 23 is defined inside the support main body 2221. At least a part of the inner peripheral surface of the support main body 2221 is a tapered surface that tapers in the downward direction. Specifically, a secondary dust accumulation cavity 2223 for accommodating the dust filtered by the second filter part 23 is formed inside the support main body 2221. The dust filtered by the second filter part 23 falls into the secondary dust accumulation cavity 2223 from the opening at the upper end of the rotating support member 222. When the cup cover 12 closes the dust discharge port 111, the opening at the lower end of the rotating support member 222 can be sealed by the cup cover 12. When the cup cover 12 opens the dust discharge port 111, the dust in the secondary dust cavity can be discharged from the dust discharge port 111. Among them, at least a part of the inner peripheral surface of the support main body 2221 is a tapered surface that tapers in the downward direction, which can guide the dust in the secondary dust accumulation cavity 2223, facilitating the quick discharge of the dust in the secondary dust accumulation cavity 2223 after the cup cover 12 opens the dust discharge port 111.

[0081] Combined Figure 9 , further, the rotary support member 222 further includes a positioning portion 2222. The positioning portion 2222 is provided inside the lower end of the support main body 2221. There is a channel 2224 extending in the vertical direction between the support main body 2221 and the positioning portion 2222. The positioning portion 2222 is rotatably sleeved outside the support column 2122. Specifically, the channel 2224 between the positioning portion 2222 and the support main body 2221 can facilitate the discharge of dust in the secondary dust accumulation cavity 2223. The positioning portion 2222 is provided inside the support main body 2221, which can make full use of the space inside the support main body 2221, cooperate with the support column 2122 to support the rotation of the first filter portion 22, make the structure of the filter device 20 compact, and improve the space utilization rate.

[0082] Exemplarily, ribs may be connected between the support main body 2221 and the positioning portion 2222, which can enhance the connection stability between the support main body 2221 and the positioning portion 2222, and facilitate the definition of the channel 2224 between the support main body 2221 and the positioning portion 2222, so as to facilitate the dust in the secondary dust accumulation cavity 2223 to be discharged from the dust discharge port 111.

[0083] Combined Figure 4 , in some embodiments of the present invention, a bearing 25 is provided between the positioning portion 2222 and the support portion 21, which reduces the friction when the rotary support member 222 rotates relative to the support shaft, improves the rotation smoothness of the first filter portion 22, and further facilitates the loosening of the filaments wound on the surface of the first filter portion 22.

[0084] Combined Figure 9 , in some embodiments of the present invention, the positioning portion 2222 is provided with a first positioning groove 22221, the lower end portion of the support column 2122 is provided with a second positioning groove 21221, the outer ring of the bearing 25 is provided in the first positioning groove 22221, and the inner ring of the bearing 25 is provided in the second positioning groove 21221. Specifically, the rotary support member 222 is rotatably connected to the support column 2122 through the bearing 25. The positioning portion 2222 is provided with the first positioning groove 22221, and the support column 2122 is provided with the second positioning groove 21221. When the rotary support member 222 is installed on the support column 2122 through the bearing 25, the cooperation of the first positioning groove 22221 and the second positioning groove 21221 can prevent the axial movement of the bearing 25, and further prevent the axial movement of the first filter portion 22, improving the structural stability of the first filter portion 22.

[0085] Combined Figure 1 and Figure 2, in some embodiments of the present invention, the second filter part 23 has a first position and a second position. The second filter part 23 locks the first filter part 22 in the first position to restrict the rotation of the first filter part 22. At this time, the first filter part 22 cannot rotate. The cooperation of the first filter part 22 and the second filter part 23 can perform two-stage filtration on the dirty air entering the dust storage cavity, improving the cleaning effect and working stability of the cleaning device 100; the second filter part 23 releases the lock on the first filter part 22 in the second position, and the first filter part 22 can rotate around the axis, which is convenient for loosening the hair wound on the surface of the first filter part 22.

[0086] In some embodiments of the present invention, the second filter part 23 abuts against the first filter part 22 in the first position and restricts the rotation of the first filter part 22. The rotation of the first filter part 22 is restricted by the direct contact between the first filter part 22 and the second filter part 23, simplifying the structure of the filtering device 20. Specifically, in the first position of the second filter part 23, the second filter part 23 contacts the first filter part 22 and applies a force to the first filter part 22 to restrict the rotation of the first filter part 22, which is convenient for filtering the dirt entering the dust cup 10 through the cooperation of the first filter part 22 and the second filter part 23, improving the working stability of the cleaning device 100.

[0087] Exemplarily, the second filter part 23 moves up and down along the direction parallel to the axis of the first filter part 22. The first position can be located above the second position. When the cup cover 12 opens the dust discharge port 111, the second filter part 23 can move downward to the second position and release the lock on the first filter part 22. When the cup cover 12 closes the dust discharge port 111, the second filter part 23 moves upward to the first position to lock the first filter part 22.

[0088] Combined with Figure 7, wherein, the upper end of the first filter part 22 has a first fitting 223, and the upper end of the second filter part 23 has a second fitting 232. In the first position, the first fitting 223 and the second fitting 232 are in contact and provide damping for the rotation of the first filter part 22. Specifically, when the second filter part 23 is in the first position, the first fitting 223 and the second fitting 232 are in contact, preventing the first filter part 22 from rotating. When the second filter part 23 moves to the second position, the position of the first filter part 22 in the axial direction is relatively fixed. Therefore, the first fitting 223 and the second fitting 232 are separated. At this time, the second filter part 23 releases the locking of the first filter part 22. By arranging the first fitting 223 at the upper end of the first filter part 22 and the second fitting 232 at the upper end of the second filter part 23, it is convenient for the second filter part 23 to contact the first filter part 22 and limit the rotation of the first filter part 22 when in the first position. When the second filter part 23 moves downward, the second filter part 23 can quickly release the locking of the first filter part 22, simplifying the structure of the filtering device 20.

[0089] Combined Figure 7 , in some embodiments of the present invention, the first filter part 22 includes a filter screen 2211 and a filter screen support 2212. The filter screen support 2212 surrounds the axis of the first filter part 22 and has a hollow structure. The filter screen 2211 is arranged on the filter screen support 2212 to cover the hollow structure, and the first fitting 223 is arranged at the upper end of the filter screen support 2212. The filter screen support 2212 can support and fix the filter screen 2211, improving the structural strength and stability of the first filter part 22. By arranging the first fitting 223 at the upper end of the filter screen support 2212, the filter screen support 2212 can be directly used to cooperate with the second filter part 23, without additionally setting a complex cooperation structure between the first filter part 22 and the second filter part 23, simplifying the structure of the filtering device 20.

[0090] Combined Figure 7 , in some embodiments of the present invention, the second filter part 23 includes a multi-cone body 233 and an upper cover plate 234. The upper cover plate 234 is connected to the upper end of the multi-cone body 233 and includes a wind guiding column 2341 communicating with the multi-cone body 233. Specifically, the second filter part 23 can be a multi-cone filtering structure. When the cleaning device 100 is in a working state, the dirty air entering the dust storage cavity of the cup body 11 passes through the first filter part 22 and then enters the interior of the first filter part 22, and flows into the multi-cone body 233 for further filtering. The airflow that has completed filtering in the multi-cone body 233 flows through the wind guiding column 2341 on the upper cover plate 234 to the suction device. Among them, the second fitting 232 can be arranged on the upper cover plate 234, and the upper cover plate 234 can be directly used to cooperate with the first filter part 22, without additionally setting a complex cooperation structure between the first filter part 22 and the second filter part 23, simplifying the structure of the filtering device 20.

[0091] Optionally, the second filtering part 23 may further include a lower cover plate 235. The lower cover plate 235 is connected to the lower end of the multi-cone body 233. In the first position, the lower cover plate 235 abuts against the first filtering part 22. The lower cover plate 235 can provide a certain damping for the rotation of the first filtering part 22. That is to say, in the first position, both the upper and lower ends of the second filtering part 23 abut against the first filtering part 22 to effectively limit the rotation of the first filtering part 22, so that the first filtering part 22 and the second filtering part 23 cooperate to filter the air flow entering the dust cup 10.

[0092] Exemplarily, the lower cover plate 235 may be provided with a rubber member. When in the first position, the rubber member abuts against the first filtering part 22. On the one hand, it can seal the space between the first filtering part 22 and the second filtering part 23. On the other hand, it can provide damping for the rotation of the first filtering part 22 through the rubber member.

[0093] In some embodiments of the present invention, the inner peripheral surface of the first fitting 223 includes a first tapered surface that tapers in the upward direction, and the outer peripheral surface of the second fitting 232 includes a second tapered surface that tapers in the upward direction. In the first position, the second tapered surface abuts against the first tapered surface. In the first position, the cooperation of the first tapered surface and the second tapered surface can stably limit the rotation of the first filtering part 22, facilitating the cooperation of the first filtering part 22 and the second filtering part 23 to filter the air flow entering the dust cup 10. When the second filtering part 23 moves from the first position to the second position, the design of the first tapered surface and the second tapered surface can facilitate the separation of the first filtering part 22 and the second filtering part 23, avoiding the first filtering part 22 from hindering the movement of the second filtering part 23. In addition, when the second filtering part 23 moves from the second position to the first position, the tapered surface can play a guiding role, thereby improving the smoothness of the second filtering part 23 during the switching between the first position and the second position.

[0094] In some embodiments of the present invention, the inner peripheral surface of the first fitting 223 further includes a first extension surface, the upper edge of the first extension surface is connected to the lower edge of the first tapered surface, the outer peripheral surface of the second fitting 232 further includes a second extension surface, and the upper edge of the second extension surface is connected to the lower edge of the second tapered surface; wherein, along the radial direction of the second tapered surface, there is a gap between the first extension surface and the second extension surface, avoiding friction between the first extension surface and the second extension surface when the second filtering part 23 moves in the up and down direction, reducing the influence on the movement of the second filtering part 23 in the axial direction, and further improving the smoothness of the second filtering part 23 during the movement.

[0095] Exemplarily, the back surface of the first extension surface can be used to cooperate with and position the filter screen main body 221, and the back surface of the second extension surface can be used to cooperate with and position the multi-cone body 233.

[0096] Combined with Figures 10 to 13, the present invention also provides a cleaning system, which includes a base station 200 and the aforementioned cleaning device 100. The base station 200 can clean the dirt in the dust cup 10 of the cleaning device 100, reducing the operation burden of the user and enhancing the convenience of the user using the cleaning device 100.

[0097] For the cleaning system according to the first aspect embodiment of the present invention, the base station 200 has a docking interface 210, and the dust cup 10 is separable and dockable with the docking interface 210. Exemplarily, an unlocking member may be provided on the base station 200. The dust cup 10 may include a cup cover 12 and a cup body 11. The cup cover 12 is used to open and close the ash discharge port 111 of the cup body 11. After the dust cup 10 is docked with the docking interface 210 of the base station 200, the unlocking member can trigger the opening of the ash discharge port 111 of the dust cup 10, that is to say, the ash discharge port 111 can be opened through a mechanical structure.

[0098] In some embodiments of the present invention, the dust cup 10 includes a cup body 11 and a cup cover 12. The cup cover 12 is used to open and close the ash discharge port 111 of the cup body 11. The docking interface 210 may have negative pressure to drive the cup cover 12 to open the ash discharge port 111, and the first filter part 22 rotates under the action of air flow driving. Specifically, during the dust suction process of the cleaning device 100, the cup cover 12 closes the ash discharge port 111. When the cleaning device 100 is docked with the base station 200 and enters the self-cleaning mode, the docking interface 210 has negative pressure. Under the action of the negative pressure, the cup cover 12 is caused to open the ash discharge port 111. At the same time, the first filter part 22 rotates under the action of air flow driving. On the one hand, the cleaning of the garbage in the cup body 11 is realized, and on the other hand, the cleaning of the first filter part 22 is realized. There is no need to additionally provide a cleaning mechanism for cleaning the first filter part 22, the structure is simpler, the cost is lower, and the first filter part 22 is not easily blocked, and the cleaning device 100 can continuously maintain a good cleaning effect.

[0099] Among them, the docking interface 210 may have negative pressure. A motor may be provided in the base station 200, and the operation of the motor causes the docking interface 210 to generate negative pressure; or, the suction device of the cleaning device 100 may be utilized, and the docking interface 210 generates negative pressure under the action of the suction device.

[0100] Combined Figure 11 and Figure 13 , for the cleaning system base station 200 according to the second aspect embodiment of the present invention, there are a dust collection air duct 220 and a bypass air duct 230 that are interconnected. The cleaning device 100 is separable and dockable with the base station 200. The cleaning device 100 has an air inlet air duct 31, a return air duct 32, and a suction air duct 33.

[0101] Among them, the cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the air inlet duct 31 is connected to the dust cup 10, and the dust cup 10 is connected to the suction duct 33. In the self-cleaning mode, the air inlet duct 31 is connected to the dust cup 10, the dust cup 10 is connected to the dust collection duct 220, and the bypass duct 230 is connected to the suction duct 33.

[0102] Exemplarily, in combination with Figure 11 , the arrows show the flow direction of the air flow of the cleaning device 100 in the working mode. The cleaning device 100 may include a suction device. In the working mode, the suction device is connected to the dust cup 10. Dirt such as dust, hair, and debris on the working surface is sucked into the dust cup 10 through the air inlet duct 31. The filtering device 20 filters the air flow, and the clean air flow after dust filtration is discharged outside the cleaning device 100 from the suction duct 33 through the suction device. In combination with Figure 11 , when the cleaning device 100 finishes the cleaning work, the cleaning device 100 can be docked to the base station 200. In the self-cleaning mode of the cleaning device 100, the cup cover 12 opens the dust discharge port 111 to connect the dust cup 10 to the dust collection duct 220, and the bypass duct 230 is connected to the suction duct 33. Under the action of the suction device, a negative pressure is generated in the base station 200, so that dirt such as dust, debris, and hair in the dust cup 10 is collected into the dust bag 240 of the base station 200. The air flow in the base station 200 flows back to the return duct 32 of the cleaning device 100 through the bypass duct 230, and finally is discharged from the suction duct 33. By providing the bypass duct 230 on the base station 200 and the return duct 32 on the cleaning device 100, the base station 200 does not need to be provided with a motor. By introducing negative pressure into the base station 200 by means of the suction device of the cleaning device 100, a negative pressure is generated in the base station 200. The negative pressure in the base station 200 can clean and collect the dirt in the dust cup 10 of the cleaning device 100, simplify the structure of the base station 200, and reduce the noise during the operation of the base station 200.

[0103] Optionally, in the working mode, the cup cover 12 closes the dust discharge port 111, and the second filtering part 23 can lock the first filtering part 22, and the first filtering part 22 will not rotate. At this time, the first filtering part 22 and the second filtering part 23 cooperate to filter the air flow entering the dust cup 10.

[0104] In combination with Figure 13, Further, in the self - cleaning mode, the air flow circulates along the air inlet duct 31, the dust cup 10, the dust collection duct 220, the bypass air duct 230, the return air duct 32 and the suction duct 33, and drives the first filter part 22 to rotate. That is to say, the air flow entering the dust cup 10 in the self - cleaning mode can be utilized to drive the first filter part 22 to rotate. Specifically, in the working mode, when the dust - laden air flow enters the dust cup 10 through the air inlet duct 31, a high - speed rotating air flow is formed in the dust cup 10, and filaments such as hair are easily wound around the outer side of the first filter part 22. When the cleaning device 100 is in the self - cleaning mode, the supporting part supports the rotation of the first filter part 22, and the air flow entering the dust cup 10 through the air inlet duct 31 can drive the first filter part 22 to rotate, so that the filaments such as hair wound around the first filter part 22 in the working mode can be loosened, and the filaments are more likely to fall off. Among them, the first filter part 22 is driven by the air flow entering the dust cup 10, so its rotation direction is the same as the rotation direction of the air flow entering the dust cup 10, and thus the same as the rotation direction of the hair wound by the air flow. Compared with the case where the first filter part 22 does not rotate, when the air flow rotates a certain number of circles in the dust cup 10, when the first filter part 22 rotates, theoretically the number of circles that the hair rotates relative to the first filter part 22 is less, that is, the number of turns of hair winding is also lower. Therefore, it is more conducive to the separation of the hair from the first filter part 22. In the self - cleaning mode, the cleaning device 100 can improve the cleaning effect of the filtering device 20, without the need to additionally set up a structure for cleaning the filtering device 20, thereby reducing the situation that the hair winding blocks the first filter part 22 and affects the filtering efficiency.
