Detailed Implementation

[0038] 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.

[0039] 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.

[0040] 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 equipment 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 equipment 100 through the suction motor 11.

[0041] The filter device 30 can extend entirely into the dust cup 20, or a portion of the filter device 30 can extend into the dust cup 20 while another portion extends out of the dust cup 20. For example, the filter device 30 can be connected to the dust cup 20, meaning that when the dust cup 20 is separated from the main body of the cleaning device 100, the filter device 30 can be separated from the main unit 10 together with the dust cup 20; or, the filter device 30 can be connected to the main unit 10, and the dust cup 20 can be detachably connected to the main unit 10. When the dust cup 20 is installed on the main unit 10, at least a portion of the filter device 30 extends into the dust cup 20 to filter dust and dirt drawn into the dust cup 20. When the dust cup 20 is separated from the main unit 10, the filter device 30 remains connected to the main unit 10. This makes it easier to disassemble the dust cup 20 when it needs to be replaced or cleaned. Since the filter device 30 is connected to the main unit 10, the disassembly and assembly of the dust cup 20 does not affect the filter device 30, improving the efficiency of the disassembly and assembly of the dust cup 20.

[0042] Combination Figure 2 and Figure 3 The filtration device 30 includes a separation mechanism 31 and a motor pre-filter 32, which is located between the separation mechanism 31 and the suction motor 11. Specifically, the airflow containing dirt entering the dust cup 20 is first filtered by the separation mechanism 31, then filtered by the motor pre-filter 32, and then 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 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.

[0043] Combination Figure 2 The main unit 10 also includes an air duct switching component 15, which is used to change the direction of airflow within the cleaning device 100.

[0044] Among them, the cleaning equipment 100 has a working mode and a self-cleaning mode, combined with Figure 2 In operating mode, the air duct switching component 15 is configured to cause the suction motor 11 to drive the airflow within the dust cup 20 to flow from the separation mechanism 31 to the motor pre-filter 32; combined with Figure 3In self-cleaning mode, the air duct switching component 15 is configured to drive the suction motor 11 to pass through the motor pre-filter 32 and flow into the separation mechanism 31. Specifically, by setting the air duct switching component 15 to change the direction of airflow, in the working mode of the cleaning device 100, the airflow flows from the separation mechanism 31 to the motor pre-filter 32 to filter the airflow entering the dust cup 20. In the self-cleaning mode, the airflow passes through the motor pre-filter 32 and flows into the separation mechanism 31 to facilitate self-cleaning of the motor pre-filter 32.

[0045] Combination Figure 2 For example, the host 10 may be provided with an air inlet duct 13. The arrow shows the airflow path in the working mode. Dust, hair, debris and other dirt on the working surface are sucked into the dust cup 20 through the air inlet duct 13. The dust and garbage carried by the dirty air are first separated by the separation mechanism 31. The separated dust and garbage remain in the dust cup 20. The separated air continues to flow to the motor pre-filter 32. After being filtered by the motor pre-filter 32, the airflow flows to the suction motor 11 and is discharged to the outside of the cleaning equipment 100.

[0046] In self-cleaning mode, the cleaning device 100 uses a suction motor 11 to drive airflow from the motor pre-filter 32 to the separation mechanism 31. During this flow, the airflow carries away dirt adhering to the motor pre-filter 32. Understandably, after prolonged use, the motor pre-filter 32 accumulates dust and other impurities. 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. This invention, in self-cleaning mode, uses the suction motor 11 to drive airflow through the motor pre-filter 32 to the separation mechanism 31, effectively cleaning the motor pre-filter 32 without requiring user disassembly or additional cleaning mechanisms. This reduces the user's workload, extends the lifespan of the suction motor 11, and solves the problem of frequent motor pre-filter 32 replacements.

[0047] The air duct switching component 15 can change the airflow direction, meaning it can switch the air duct of the cleaning device 100. For example, the air duct switching component 15 can be operated by the user. For instance, the cleaning device 100 may have an operating unit that allows the air duct switching component 15 to switch the air duct, thus changing the airflow direction within the cleaning device 100. Alternatively, the air duct switching component 15 can switch the air duct by cooperating with a structure corresponding to the base station 200. For example, the base station 200 may have a trigger unit that, after the cleaning device 100 is connected to the base station 200, triggers the air duct switching component 15 to switch the air duct, eliminating the need for additional user operation and simplifying the user's steps. Figure 3 The separation mechanism 31 includes a rotatable first filter section 311 and a second filter section 312 located downstream of the first filter section 311. The first filter section 311 is rotatable. "Downstream" refers to the rearmost 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 second filter section 312 is located downstream of the first filter section 311. After the dust-laden airflow enters the dust cup 20, it first passes through the first filter section 311 and then through the second filter section 312. The first filter section 311 can filter larger dust particles such as debris, hair, and other contaminants, while the second filter section 312 can filter smaller dust particles. Understandably, when the cleaning device 100 is vacuuming, the dust-laden airflow enters the dust cup 20, forming a high-speed rotating airflow inside the dust cup 20. Hair and other filamentous materials are easily wrapped around the outside of the first filter section 311, which can easily cause the first filter section 311 to become clogged after prolonged use. The rotatable first filter section 311 can loosen the hair and other filamentous materials wrapped around its surface, making it easier to separate the hair and other filamentous materials from the first filter section 311 and making it easier to clean the first filter section 311. This makes the filter device 30 less prone to clogging, allowing the cleaning device 100 to maintain a good cleaning effect even after prolonged use.

[0048] According to the cleaning device 100 of this utility model embodiment, in self-cleaning mode, the suction motor 11 drives the airflow through the motor pre-filter 32 and flows to the separation mechanism 31, which can clean the motor pre-filter 32, improve the service life of the suction motor 11, and reduce the user's operating burden.

[0049] In the self-cleaning mode, the suction motor 11 drives the airflow through the motor pre-filter 32 to the separation mechanism 31. For example, the cleaning device 100 can be connected to the base station 200, and the cleaning device 100 can be cleaned through the base station 200. The host 10 can be provided with a make-up air channel. In the self-cleaning mode, the air duct switching component 15 opens the make-up air duct, the suction motor 11 works, and the base station 200 forms a suction negative pressure on the dust cup 20. The airflow enters the motor pre-filter 32 through the make-up air channel and flows to the separation mechanism 31 to remove the dust attached to the motor pre-filter 32, thereby cleaning the motor pre-filter 32. Alternatively, in the self-cleaning mode, the suction motor 11 can blow air in the opposite direction to the motor pre-filter 32 to drive the airflow from the motor pre-filter 32 to the separation mechanism 31.

[0050] 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.

[0051] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the main unit 10 is provided with a connecting port 12 that is opened and closed by an air duct switching component 15. The connecting port 12 is located on the side of the motor pre-filter 32 away from the separation mechanism 31. In the working mode, the connecting port 12 is closed, and in the self-cleaning mode, the connecting port 12 is open. The suction motor 11 drives the airflow through the connecting port 12 and passes through the motor pre-filter 32 from the side of the motor pre-filter 32 away from the separation mechanism 31. Exemplarily, the connecting port 12 can be connected to the outside atmosphere. In the working mode, the connecting port 12 is closed by the air duct switching component 15 to prevent airflow from leaking out of the connecting port 12 and affecting the suction efficiency of the suction motor 11. In the self-cleaning mode, combined with Figure 8 As shown, the connection port 12 is opened by the air duct switching component 15, allowing airflow to enter the motor pre-filter 32 for cleaning. By providing the connection port 12 on the main unit 10 and opening and closing it via the air duct switching component 15, self-cleaning of the motor pre-filter 32 can be achieved without the need for a complex air duct structure on the main unit 10.

[0052] For example, the housing of the main unit 10 may be provided with an air inlet. In self-cleaning mode, the air duct switching component 15 opens the connection port 12, and the airflow enters the main unit 10 from the air inlet and blows towards the motor pre-filter 32 through the connection port 12 to clean the dirt attached to the motor pre-filter 32, thereby achieving self-cleaning of the motor pre-filter 32. In working mode, the air duct switching component 15 closes the connection port 12, and when the suction motor 11 is working, it can prevent the airflow filtered by the motor pre-filter 32 from leaking out from the air inlet.

[0053] Combination Figure 2 and Figure 8 In some embodiments of this utility model, the host 10 has an air inlet duct 13 and a self-cleaning air duct 14 that connects to the base station 200, and the air inlet duct 13 connects to the dust cup 20.

[0054] Combination Figure 2 In operating mode, the air duct switching component 15 connects the suction motor 11 and the dust cup 20, combined with... Figure 3 In self-cleaning mode, the air duct switching component 15 connects the suction motor 11 and the self-cleaning air duct 14. Specifically, in operating mode, the cleaning device 100 combines... Figure 2 As shown, the arrows indicate the airflow direction of the cleaning device 100 in its working mode. The air duct switching component 15 connects the suction motor 11 to the dust cup 20. The suction head of the cleaning device 100 draws dust, hair, debris, and other contaminants from the work surface into the dust cup 20 through the air inlet duct 13. The dust cup 20 is in a closed state and the airflow is filtered by the filter device 30. The airflow first passes through the separation mechanism 31 for filtration, and then through the motor pre-filter 32 for filtration. The filtered clean airflow is then discharged from the cleaning device 100 via the suction motor 11. Figure 3 and Figure 8 As shown, 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 15 connects the suction motor 11 to the self-cleaning air duct 14, and the dust cup 20 can be connected to the base station 200. The base station 200 is also connected to the self-cleaning air duct 14. Under the action of the suction motor 11, a negative pressure is generated in the base station 200, which causes the dust, debris, hair and other dirt in the dust cup 20 to be 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 14 and is discharged to the outside of the cleaning device 100 through the suction motor 11. By setting a self-cleaning air duct 14 and an air duct switching component 15 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.

[0055] Combination Figure 6 and Figure 7Furthermore, the air duct switching assembly 15 includes a switching body 151 and a first seal 152. The switching body 151 connects to the dust cup 20, the suction motor 11, and the self-cleaning air duct 14. The first seal 152 connects to the switching body 151 and controls the suction motor 11 to selectively connect to the dust cup 20 and the self-cleaning air duct 14. Specifically, in the working mode, the first seal 152 controls the suction motor 11 to connect to the dust cup 20, so that the airflow filtered by the filter device 30 is discharged to the outside of the cleaning equipment 100 through the suction motor 11. In the self-cleaning mode, the first seal 152 controls the suction motor 11 to connect to the self-cleaning air duct 14. By setting the switching body 151 and the first seal 152 to cooperate, the structure of the air duct switching assembly 15 is simplified, making it easier for the cleaning equipment 100 to switch air ducts in different modes.

[0056] Combination Figure 6 and Figure 7 The duct switching assembly 15 also includes a second seal 153, which is connected to the switching body 151 and used to open and close the communication port 12. Specifically, in conjunction with Figure 7 In the working mode, the second seal 153 closes the connection port 12 to prevent the airflow flowing through the motor pre-filter 32 from leaking out of the connection port 12. In the self-cleaning mode, the second seal 153 opens the connection port 12 to facilitate the suction motor 11 to drive the airflow through the connection port 12 into the motor pre-filter 32 for self-cleaning.

[0057] Furthermore, the first seal 152 is rotatably connected to the switching body 151, and the second seal 153 is rotatably connected to the switching body 151. The position of the switching body 151 is relatively fixed. Rotating the first seal 152 can realize the switching of the air duct, thereby facilitating the switching of the air duct by the air duct switching component 15 and improving the convenience of using the cleaning equipment 100. Rotating the second seal 153 can realize the opening and closing of the connection port 12, making it easy to control the closing of the connection port 12 in different modes.

[0058] For example, the switching body 151 has an airflow conversion chamber and a first interface, a second interface and a third interface that connect to the airflow conversion chamber. The first interface connects to the dust cup 20, the second interface connects to the self-cleaning air duct 14 and the third interface connects to the suction motor 11. In the working mode, the first interface is connected to the third interface, and in the self-cleaning mode, the second interface is connected to the third interface. Specifically, the air duct switching assembly 15 can be located upstream of the suction motor 11. By setting an airflow conversion chamber in the switching body 151, the air outlet of the dust cup 20 is fluidly connected to the airflow conversion chamber through a first interface, the self-cleaning air duct 14 is fluidly connected to the airflow conversion chamber through a second interface, and the airflow conversion chamber is fluidly connected to the suction motor 11 through a third interface. The first seal 152 can selectively close and seal either the first or second interface. In the working mode, the first seal 152 covers the second interface to control the dust cup 20 to be fluidly connected to the suction motor 11 through the airflow conversion chamber. In the self-cleaning mode, the first seal 152 covers the first interface to control the self-cleaning air duct 14 to be fluidly connected to the suction motor 11 through the airflow conversion chamber. By setting the switching body 151, it is convenient to connect the air duct switching assembly 15 to the suction motor 11, the dust cup 20, and the self-cleaning air duct 14, and it is also convenient for the cleaning equipment 100 to switch air ducts in different working modes.

[0059] Combination Figure 6 and Figure 7 In some embodiments of this utility model, the host 10 further includes a transmission assembly 16, which includes a transmission rod 161. The transmission rod 161 extends in a direction parallel to the axis of the dust cup 20 and is movable in a direction parallel to the axis of the dust cup 20.

[0060] The transmission assembly 16 also includes a rotating part 162, which is connected to the first seal 152 and the second seal 153 respectively. The rotating part 162 is used to drive the first seal 152 and the second seal 153 to rotate synchronously.

[0061] The transmission assembly 16 also includes a transmission part 163, which is rotatably connected to the switching body 151. One end of the transmission part 163 is opposite to the transmission rod 161, and the other end of the transmission part 163 is connected to the rotating part 162. The transmission part 163 is configured to convert the translational motion of the transmission rod 161 into the rotational motion of the rotating part 162.

[0062] For example, the base station 200 may be provided with a triggering unit. The cleaning device 100 can be separated from and connected to the base station 200 along the vertical direction, that is, along the axis of the dust cup 20. After the cleaning device 100 is connected to the base station 200, the triggering unit pushes the transmission rod 161 to move upward. The transmission rod 161 drives one end of the transmission part 163 to move upward. The other end of the transmission part 163 converts the translational motion of the transmission rod 161 along the vertical direction into the rotational motion of the rotating part 162, thereby driving the first sealing member 152 and the second sealing member 153 to rotate synchronously, so that the first sealing member 152 controls the suction motor 11 to connect to the self- The cleaning duct 14 is opened, and the second seal 153 opens the connection port 12. The suction motor 11 operates, creating negative pressure inside the base station 200. Dust, debris, hair, and other contaminants in the dust cup 20 assembly are collected in the base station 200. The airflow inside the base station 200 flows back to the suction motor 11 through the cleaning duct 14 and is discharged by the suction motor 11. Simultaneously, the airflow enters the motor pre-filter 32 through the connection port 12. As the airflow passes through the motor pre-filter 32, it cleans the contaminants adhering to the surface of the motor pre-filter 32. The dust-laden airflow can be collected into the base station 200 through the separation mechanism 31. By setting up the transmission rod 161, the rotating part 162, and the transmission part 163 in cooperation, and with the first seal 152 and the second seal 153 rotating synchronously, after the cleaning equipment 100 is connected to the base station 200, the switching of the air duct and the opening of the connection port 12 can be realized simultaneously, simplifying the user's operation steps and improving the convenience of using the cleaning equipment 100.

[0063] Optionally, the transmission assembly 16 further includes a reset member, which connects the transmission part 163 and the switching body 151. After the cleaning device 100 is separated from the base station 200, the reset member has an elastic force to drive the transmission part 163 to reset. Specifically, after the cleaning device 100 is separated from the base station 200, the trigger part of the base station 200 releases the transmission rod 161. Under the action of the reset member, the transmission part 163 is driven to reset, and the transmission rod 161 is driven to move downward. At this time, the first sealing member 152 controls the suction motor 11 to connect to the dust cup 20, and the second sealing member 153 closes the connection port 12, so that the cleaning device 100 can vacuum the working surface.

[0064] Combination Figure 2 and Figure 5 For example, the main unit 10 may be provided with a suction port 17, which is located on the side of the motor pre-filter 32 away from the separation mechanism 31. In the working mode, the air duct switching component 15 controls the suction port 17 to open, and in the self-cleaning mode, the air duct switching component 15 controls the suction port 17 to close. Specifically, in the working mode, the first seal 152 opens the suction port 17 and closes the channel between the self-cleaning air duct 14 and the suction motor 11. In the self-cleaning mode, the first seal 152 closes the suction port 17 and opens the channel between the self-cleaning air duct 14 and the suction motor 11.

[0065] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the air duct switching component 15 is disposed between the suction motor 11 and the motor pre-filter 32, making the structure of the cleaning device 100 more compact. In conjunction with the foregoing, in the working mode, the air duct switching component 15 can open the airflow channel between the suction motor 11 and the dust cup 20, that is, the airflow channel between the suction motor 11 and the motor pre-filter 32, so that the suction motor 11 can drive the airflow in the dust cup 20 to flow from the separation mechanism 31 to the motor pre-filter 32. In the self-cleaning mode, the air duct switching component 15 can open the connecting port 12, so that the suction motor 11 can drive the airflow to flow from the motor pre-filter 32 to the separation mechanism 31. The air duct switching component 15 is disposed between the suction motor 11 and the motor pre-filter 32, which facilitates the switching of the air duct of the cleaning device 100 in different modes.

[0066] In some embodiments of this utility model, in the self-cleaning mode, the suction motor 11 drives the airflow through the motor pre-filter 32 and into the separation mechanism 31, which can clean the inside of the separation mechanism 31 and improve the cleaning effect of the filter device 30 in the self-cleaning mode.

[0067] For example, the filtration device 30 may include a first filter section 311 and a second filter section 312. The second filter section 312 is located downstream of the first filter section 311. The first filter section 311 may include an annular filter screen to perform primary filtration of dirt entering the dust cup 20. The second filter section 312 may include a multi-cone cyclone separator, etc. The second filter section 312 is located downstream of the first filter section 311 and can perform secondary filtration of the airflow filtered by the first filter section 311. In self-cleaning mode, the suction motor 11 can drive airflow through the motor pre-filter 32 and into the inside of the second filter section 312, which can simultaneously clean the motor pre-filter 32 and the second filter section 312, improving the cleaning effect of the filtration device 30.

[0068] In some embodiments of this utility model, in self-cleaning mode, the suction motor 11 also drives airflow from the air inlet duct 13 into the dust cup 20, and the first filter section 311 can be driven to rotate by the airflow entering the dust cup 20 from the air inlet duct 13. Exemplarily, after the cleaning device 100 completes the cleaning work, the cleaning device 100 can be connected to the base station 200. In self-cleaning mode, the dust discharge port of the dust cup 20 is opened, so that the dust cup 20 is connected to the dust bag of the base station 200. 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 into the dust bag of the base station 200. The airflow in the base station 200 can flow back to the cleaning device 100 and finally be discharged by the suction motor 11. In self-cleaning mode, the cleaning device 100 can clean the dirt in the dust cup 20. At the same time, the airflow entering the dust cup 20 can also drive the first filter 311 to rotate, which facilitates the loosening of dirt wrapped on the surface of the first filter 311 and realizes the self-cleaning of the first filter 311.

[0069] For example, a first blade may be provided on the outer side of the first filter section 311. Specifically, the first blade is adapted to be driven by the airflow entering the dust cup 20 through the air inlet channel. For example, when the cleaning device 100 is in self-cleaning mode, the base station 200 may have negative pressure, driving the airflow from the air inlet channel 13 into the dust cup 20 to collect the dirt in the dust cup 20 into the base station 200. Providing the first blade on the outer side of the first filter section 311 can, on the one hand, push the first filter section 311 to rotate under the action of airflow, and on the other hand, can also prevent hair and other objects from getting tangled on the outer side of the first filter section 311.

[0070] The first blade may include multiple blades arranged in a circumferential direction.

[0071] In some embodiments of this utility model, in the self-cleaning mode, the suction motor 11 drives the airflow from the motor pre-filter 32 into the separation mechanism 31. The first filter section 311 is driven to rotate by the airflow from the motor pre-filter 32 into the separation mechanism 31. That is, the first filter section 311 can be driven to rotate by the airflow inside. While cleaning the motor pre-filter 32 and the interior of the separation mechanism 31, it can also loosen the hair and other dirt wrapped around the surface of the first filter section 311, thereby improving the cleaning effect of the filter device 30 in the self-cleaning mode.

[0072] For example, a second blade may be provided on the inner side of the first filter section 311. Specifically, the second blade is adapted to be driven by airflow entering the separation mechanism 31 from the motor pre-filter 32. For example, when the cleaning device 100 is in self-cleaning mode, the base station 200 may have negative pressure, driving airflow from the motor pre-filter 32 to the separation mechanism 31 to perform self-cleaning of the motor pre-filter 32 and the interior of the separation mechanism 31. The second blade provided on the inner side of the first filter section 311 can push the first filter section 311 to rotate from the inside under the action of airflow.

[0073] In some embodiments of this utility model, in the self-cleaning mode, the first filter section 311 is simultaneously driven to rotate by the airflow entering the separation mechanism 31 from the motor pre-filter 32 and the airflow entering the dust cup 20 from the air inlet duct 13. That is, the first filter section 311 is driven to rotate by the airflow from both the inner and outer sides, so that the first filter section 311 can rotate stably in the self-cleaning mode and loosen the dirt wrapped around the surface during the rotation process, thereby improving the cleaning efficiency of the first filter section 311 and avoiding problems such as the first filter section 311 becoming clogged and causing a decrease in the suction power of the cleaning device 100.

[0074] In conjunction with the foregoing, the cleaning device 100 can interface with the base station 200. The cleaning device 100 may also include an air duct switching component 15, which may include a first seal 152 and a second seal 153. In self-cleaning mode, the first seal 152 opens the channel between the self-cleaning air duct 14 and the suction motor 11, and closes the channel between the dust cup 20 and the suction motor 11. The second seal 153 opens the communication port 12 on the main unit 10. The base station 200 generates negative pressure on the dust cup 20, allowing a portion of the airflow to enter the dust cup 20 from the air inlet duct 13, thus separating the separation mechanism 31. Hair and debris entangled on the outer surface, as well as debris between the outer surface of the separation mechanism 31 and the inner surface of the dust cup 20, are brought into the base station 200. Another part of the airflow enters the main unit 10 from the air supply port and blows towards the motor pre-filter 32 through the connecting port 12, blowing the debris from the motor pre-filter 32 towards the second filter section 312, and then into the base station 200 through the second filter section 312, thereby achieving the effect of cleaning the motor pre-filter 32. At the same time, the airflow passing through the motor pre-filter 32 enters the interior of the second filter section 312, achieving a cleaning effect on the interior of the second filter section 312.

[0075] 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 lid 22 is provided with a damping member 221. When the cup lid 22 closes the cup body 21, the damping member 221 abuts against the first filter part 311 and restricts the rotation of the first filter part 311. When the cup lid 22 opens the cup body 21, the damping member 221 releases the restriction on the rotation of the first filter part 311. 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 cup body 21, the damping member 221 presses the first filter part 311 upward, preventing the first filter part 311 from rotating. This allows the filtering device 30 to filter the dust-laden airflow entering the dust cup 20, preventing the rotation of the first filter part 311 from affecting the filtering effect of the filtering device 30. For example, the damping member 221 can be a rubber part.

[0076] In some embodiments of this utility model, when the cup lid 22 closes the cup body 21, the second filter part 312 engages with the first filter part 311, restricting the rotation of the first filter part 311. Specifically, when the cup lid 22 closes the cup body 21, the second filter part 312 contacts the first filter part 311 and applies a force to it, restricting the rotation of the first filter part 311. This keeps the first filter part 311 and the second filter part 312 relatively stationary, 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 311 from affecting the filtration effect of the filter device 30.

[0077] 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 cup body 21, the damping member 221 abuts against the first filter part 311 and restricts the rotation of the first filter part 311. The second filter part 312 abuts against the first filter part 311 and restricts the rotation of the first filter part 311. At this time, since the cup lid 22 is closed, the damping member 221 on the cup lid 22 presses the first filter part 311 upward, so that the upper end of the first filter part 311 abuts against the second filter part 312, and the lower end of the first filter part 311 abuts against the damping member 221, thereby fixing the first filter part 311 and preventing it from rotating, improving the structural stability of the first filter part 311 when the cup lid 22 is closed, and thus improving the working stability of the cleaning device 100 during the vacuuming process.

[0078] Combination Figure 8 This utility model also proposes a cleaning system, including: a base station and the aforementioned cleaning equipment. The cleaning equipment is detachable and dockable with the base station.

[0079] The base station has interconnected dust collection ducts and bypass ducts, and the main unit can have an air inlet duct and a self-cleaning duct. In the self-cleaning mode, the suction motor drives the airflow to flow sequentially through the motor pre-filter, separation mechanism, dust cup, dust collection duct, bypass duct, self-cleaning duct, and suction motor. The driving airflow also flows sequentially through the air inlet duct, dust cup, dust collection duct, bypass duct, and suction motor. The base station 200 does not need to be equipped with a motor. By using the suction motor 11 of the cleaning device 100, a negative pressure is generated inside the base station 200. The negative pressure inside the base station 200 can clean and collect dirt from 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.

[0080] Specifically, in self-cleaning mode, the cleaning system 1000 has two self-cleaning air ducts 14. The airflow direction of the first self-cleaning air duct 14 is: outside atmosphere - motor pre-filter 32 - separation mechanism 31 - dust cup 20 - base station 200 - suction motor 11, so as to achieve self-cleaning of the inside of the motor pre-filter 32 and the separation mechanism 31. The airflow direction of the second self-cleaning air duct 14 is: outside atmosphere - air inlet duct 13 - dust cup 20 - dust collection duct 210 of base station 200 - dust bag of base station 200 - bypass ventilation duct 220 of base station 200 - self-cleaning air duct 14 of cleaning equipment 100 - suction motor 11 - outside atmosphere, so as to achieve cleaning of dust cup 20.

[0081] The separation mechanism 31 may include a first filter section 311 and a second filter section 312 located downstream of the first filter section 311. In the self-cleaning mode, the suction motor drives the airflow to flow sequentially through the air inlet duct, dust cup, dust collection duct, bypass duct and suction motor, and drives the first filter section to rotate to loosen the hair wrapped around the surface of the first filter section 311.

[0082] By setting two self-cleaning air ducts 14, in self-cleaning mode, the airflow cleans the inside of the motor pre-filter and the second filter section 312 when flowing through the first self-cleaning air duct 14, and cleans the dirt in the dust cup 20 when flowing through the second self-cleaning air duct 14. At the same time, it can also drive the first filter section 311 to rotate to loosen the hair wrapped around the surface of the first filter section 311. While achieving self-cleaning of the dust cup 20, it can also perform a comprehensive cleaning of the filter device 30, improving the self-cleaning effect of the filter device 30 and enhancing the convenience of the user in using the cleaning equipment 100.

[0083] In the self-cleaning mode, the suction motor 11 drives the airflow to flow sequentially through the motor pre-filter 32, the separation mechanism 31, the dust cup 20, the base station 200, and the suction motor 11, and the driving airflow flows sequentially through the dust cup 20, the base station 200, and the suction motor 11, so as to clean the dust cup 20 and the filter device 30 of the cleaning equipment 100 in the self-cleaning mode, thereby improving the cleaning effect of the cleaning equipment 100.

[0084] Furthermore, the main unit 10 may also include an air duct switching component 15. In the working mode, the air duct switching component 15 connects the suction motor 11 and the dust cup 20. In the self-cleaning mode, the air duct switching component 15 connects the suction motor 11 and the self-cleaning air duct 14. In other words, the air duct can be switched between different modes through the air duct switching component 15.
