[0004] Cleaning equipment typically includes a separation device, a suction head, a suction device, and a dust cup. The suction head draws in external dirt and directs it into the dust cup, where the separation device separates it, allowing the dirt to remain in the dust cup.

In related technologies, base stations are used to clean the dirt from the dust cup of the cleaning equipment, reducing the user's operational burden. However, base stations usually require additional structures such as motors to create negative pressure within the base station, making the overall structure of the base station complex and increasing the cost of the entire cleaning system.

Detailed Implementation

[0054] 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.

[0055] Combination Figure 1 and Figure 2 According to the embodiment of the present utility model, the cleaning device 100 has a working mode and a self-cleaning mode. In the working mode, the cleaning device 100 can be used to clean the working surface. In the self-cleaning mode, the cleaning device 100 can cooperate with the base station 200 to clean the dust and dirt in the dust cup assembly 20, thereby realizing the self-cleaning of the cleaning device 100.

[0056] The cleaning device 100 includes a main body 10, which includes a connecting pipe 11. The connecting pipe 11 has an air inlet duct 111 for connecting to a suction head. The main body 10 also has a return air duct 112 for connecting to a base station 200. At least a portion of the return air duct 112 is located within the connecting pipe 11. Specifically, the entire return air duct 112 may be located within the connecting pipe 11, or only a portion of the return air duct may be located within the connecting pipe 11.

[0057] The cleaning device 100 also includes a dust cup assembly 20, which is configured to filter the airflow entering through the air inlet duct 111. For example, the dust cup assembly 20 may contain a filter. When the cleaning device 100 is in operation, dust-laden airflow enters the dust cup assembly 20 from the air inlet duct 111. The filter can separate and filter the dirty air entering the dust cup assembly 20, and the dust and impurities filtered out are collected in the dust storage chamber of the dust cup assembly 20.

[0058] The cleaning device 100 also includes a suction device 30, which provides negative pressure. Under this negative pressure, the cleaning device 100 can suck dust, hair, and other contaminants from the working surface into the dust cup assembly 20. Furthermore, in self-cleaning mode, the cleaning device 100 can generate negative pressure in the base station 200. This means the base station 200 does not require a motor; by using the suction device 30, negative pressure is introduced into the base station 200, which cleans the dust cup assembly 20, simplifying the structure of the base station 200 and reducing noise during operation.

[0059] Combination Figure 2 The cleaning equipment 100 also includes an air duct switching component 40, which is located on the main body 10 and configured to selectively connect the suction device 30 to the dust cup assembly 20 and the return air duct 112. In the working mode, the air duct switching component 40 connects the suction device 30 and the dust cup assembly 20; in the self-cleaning mode, the air duct switching component 40 connects the suction device 30 and the return air duct 112.

[0060] Specifically, in combination Figure 2 When the cleaning equipment 100 is in working mode, the air duct switching component 40 connects the suction device 30 to the dust cup assembly 20. Figure 2 The middle arrow indicates the airflow direction. The suction head draws dust, hair, debris, and other contaminants from the work surface into the dust cup assembly 20 through the air inlet duct 111. The dust cup assembly 20 is in a closed state and filters the airflow. The clean airflow filtered by the dust cup assembly 20 is discharged outside the cleaning device 100 via the suction device 30. After the cleaning device 100 completes its cleaning work, it can be connected to the base station 200. In self-cleaning mode, the air duct switching component 40 connects the suction device 30 to the return air duct 112. The dust cup assembly 20 can be connected to the base station 200, and the base station 200 is connected to the return air duct 112. Under the action of the suction device 30, a negative pressure is generated inside the base station 200, causing the dust, debris, hair, and other contaminants in the dust cup assembly 20 to be collected inside the base station 200. The airflow inside the base station 200 flows back to the suction device 30 through the return air duct 112 and is discharged outside the cleaning device 100 via the suction device 30. By setting a return air duct 112 and an air duct switching component 40 on the cleaning equipment 100, the base station 200 does not need to be equipped with a motor. By using the suction device 30 of the cleaning equipment 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 dirt from the dust cup component 20 of the cleaning equipment 100, simplifying the structure of the base station 200 and reducing the noise of the base station 200 during operation.

[0061] Combination Figure 1 and Figure 2The connecting pipe 11 has an air inlet duct 111. One end of the air inlet duct 111 can be fluidly connected to the dust storage chamber of the dust cup assembly 20, and the other end can be fluidly connected to the outside. At least a part of the return air duct 112 is provided in the connecting pipe 11, which optimizes the air duct layout of the cleaning equipment 100, simplifies the structure of the cleaning equipment 100, and makes the structure of the cleaning equipment 100 more compact.

[0062] According to the present invention, the cleaning device 100 is provided with a return air duct 112 and an air duct switching component 40 on its main body. This facilitates the introduction of negative pressure into the base station 200 by means of the suction device 30 of the cleaning device 100. The base station 200 does not need to be equipped with a motor, and the cleaning device 100 can be self-cleaned. In addition, the connecting pipe 11 has an air inlet duct 111, and at least a part of the return air duct 112 is provided in the connecting pipe 11. This optimizes the air duct layout of the cleaning device 100, simplifies the structure of the cleaning device 100, and makes the structure of the cleaning device 100 more compact.

[0063] For example, the cleaning device 100 can be a vacuum cleaner, a robot vacuum cleaner, a mite remover, a floor scrubber, etc. This utility model mainly uses a vacuum cleaner as an example for explanation.

[0064] The air duct switching component 40 is configured to selectively connect the suction device 30 to the dust cup assembly 20 and the return air duct 112. In other words, the air duct can be switched via the air duct switching component 40. For example, the air duct switching component 40 can be operated by the user; for instance, the cleaning device 100 may have an operating unit that allows the air duct switching component 40 to switch the air duct. Alternatively, the air duct switching component 40 can switch the air duct by cooperating with a structure corresponding to the base station 200. For example, in conjunction with... Figure 11 The base station 200 may be equipped with a trigger unit 230. After the cleaning equipment 100 is connected to the base station 200, the trigger unit 230 triggers the air duct switching component 40 to switch the air duct, which does not require the user to perform any additional operations and simplifies the user's operation steps.

[0065] In addition, the air duct switching component 40 can be a multi-way valve, which is connected to the dust cup component 20, the return air duct 112 and the suction device 30 respectively. The air duct can be switched by changing the position of the valve.

[0066] Combination Figure 2 and Figure 5In some embodiments of this utility model, the air duct switching assembly 40 includes a switching body 41 and a sealing switching element 42. The switching body 41 connects the dust cup assembly 20, the suction device 30, and the return air duct 112. The sealing switching element 42 is connected to the switching body 41 and is used to control the suction device 30 to selectively connect to the dust cup assembly 20 and the return air duct 112. Specifically, in the working mode, the sealing switching element 42 controls the suction device 30 to connect to the dust cup assembly 20; in the self-cleaning mode, the sealing switching element 42 controls the suction device 30 to connect to the return air duct 112. By setting the switching body 41 and the sealing switching element 42 in cooperation, the structure of the air duct switching assembly 40 is simplified, making it easier for the cleaning equipment 100 to switch the air duct in different modes.

[0067] Furthermore, the sealing switching component 42 is rotatably connected to the switching body 41. The position of the switching body 41 is relatively fixed. Rotating the sealing switching component 24 can realize the switching of the air duct, thereby facilitating the switching of the air duct by the air duct switching component 40 and improving the convenience of using the cleaning equipment 100.

[0068] Union Figure 3 and Figure 4 In some embodiments of this utility model, the main body 10 further includes a transmission assembly 12, which includes a transmission rod 121. The transmission rod 121 extends along a direction parallel to the axis of the dust cup assembly 20 and is movable along the same direction. Figure 2 and Figure 3 As shown, the axial direction of the dust cup assembly 20 is the AA direction.

[0069] The transmission assembly 12 also includes a rotating part 122, which is connected to the sealing switching member 42 and is used to drive the sealing switching member 42 to rotate.

[0070] The transmission assembly 12 also includes a transmission part 123, which is rotatably connected to the switching body 41. One end of the transmission part 123 is opposite to the transmission rod 121, and the other end of the transmission part 123 is connected to the rotating part 122. The transmission part 123 is configured to convert the translational motion of the transmission rod 121 into the rotational motion of the rotating part 122.

[0071] For example, combined Figure 3 and Figure 11The base station 200 may be equipped with a triggering part 230. 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 assembly 20. After the cleaning device 100 is connected to the base station 200, the triggering part 230 pushes the transmission rod 121 to move upward. The transmission rod 121 drives one end of the transmission part 123 to move upward. The other end of the transmission part 123 converts the vertical translational motion of the transmission rod 121 into the rotational motion of the rotating part 122, thereby driving the sealing switching member 42 to rotate. The sealing switching member 42 controls the suction device 30 to connect to the return air duct 112. The suction device 30 works, creating a negative pressure inside the base station 200. Dust, debris, hair and other dirt in the dust cup assembly 20 are collected in the base station 200. The airflow inside the base station 200 flows back to the suction device 30 through the return air duct 112 and is discharged through the suction device 30. By setting up the transmission rod 121, the rotating part 122 and the transmission part 123 in cooperation, the air duct can be switched simultaneously after the cleaning equipment 100 is connected to the base station 200, which simplifies the user's operation steps and improves the user's convenience in using the cleaning equipment 100.

[0072] Combination Figure 3 Optionally, the transmission assembly 12 further includes a reset member 124, which connects the transmission part 123 and the switching body 41. After the cleaning device 100 is separated from the base station 200, the reset member 124 has an elastic force to drive the transmission part 123 to reset. Specifically, after the cleaning device 100 is separated from the base station 200, the trigger part 230 of the base station 200 releases the transmission rod 121. Under the action of the reset member 124, the transmission part 123 is driven to reset, and the transmission rod 121 is driven to move downward. At this time, the sealing switching member 42 controls the suction device 30 to connect to the dust cup assembly 20 so that the cleaning device 100 can vacuum the working surface.

[0073] Combination Figure 2 In some embodiments of this utility model, the inlet 112a of the return air duct 112 is located on the side of the inlet air duct 111 near the dust cup assembly 20, which can make full use of the space between the inlet air duct 111 and the dust cup assembly 20, making the structure of the cleaning device 100 more compact. For example, the inlet 112a of the return air duct 112 may be provided with a second connector 132 that connects to the base station 200. The base station 200 may be provided with a secondary connector 242. After the second connector 132 connects to the secondary connector 242, it is convenient for the base station 200 to connect to the return air duct 112 to realize the return of airflow of the base station 200. By providing the inlet 112a of the return air duct 112 on the side of the inlet air duct 111 near the dust cup assembly 20, it is possible to prevent the user from accidentally touching the second connector 132 during the use of the cleaning device 100.

[0074] Combination Figure 1One end of the transmission rod 121 extends to the outside of the inlet 112a of the return air duct 112, and the other end of the transmission rod 121 is connected to the sealing switching element 42 to drive the sealing switching element 42 to rotate. The fact that one end of the transmission rod 121 is located outside the inlet 112a of the return air duct 112 prevents the transmission rod 121 from being exposed, thus avoiding accidental contact by the user during the use of the cleaning equipment 100 and preventing accidental switching of the air duct.

[0075] Combination Figure 5 In some embodiments of this utility model, the switching body 41 has an airflow conversion chamber 411 and a first interface 412, a second interface 413 and a third interface 414 that connect the airflow conversion chamber 411. The first interface 412 connects to the dust cup assembly 20, the second interface 413 connects to the return air duct 112, and the third interface 414 connects to the suction device 30. In the working mode, the first interface 412 is connected to the third interface 414. In the self-cleaning mode, the second interface 413 is connected to the third interface 414. Specifically, the air duct switching component 40 can be located upstream of the suction device 30. By setting an airflow conversion chamber 411 in the switching body 41, the air outlet of the dust cup assembly 20 is fluidly connected to the airflow conversion chamber 411 through the first interface 412, the return air duct 112 is fluidly connected to the airflow conversion chamber 411 through the second interface 413, and the airflow conversion chamber 411 is fluidly connected to the suction device 30 through the third interface 414. The sealing switching component 42 can selectively close and seal the first interface 412 and the second interface 413. In the working mode, the sealing switching component 42 covers the second interface 413 to control the dust cup assembly 20 to be fluidly connected to the suction device 30 through the airflow conversion chamber 411. In the self-cleaning mode, the sealing switching component 42 covers the first interface 412 to control the return air duct 112 to be fluidly connected to the suction device 30 through the airflow conversion chamber 411. By setting the switching body 41, it is convenient to connect the air duct switching component 40 with the suction device 30, the dust cup component 20 and the return air duct 112, and it is also convenient for the cleaning equipment 100 to switch the air duct in different working modes.

[0076] Combination Figure 6 In some embodiments of this utility model, at least a portion of the return air duct 112 surrounds the inlet air duct 111. Specifically, the entire return air duct 112 may surround the inlet air duct 111; or, a portion of the return air duct 112 may surround the inlet air duct 111. By surrounding the inlet air duct 111 with at least a portion of the return air duct 112, the air duct layout of the cleaning device 100 is optimized. The return air duct 112 can make full use of the space around the inlet air duct 111, making the structure of the cleaning device 100 compact, and ensuring that the return air duct 112 has a sufficiently large flow area to reduce the resistance of airflow during the return process.

[0077] For example, the return air duct 112 may be partially surrounded on one side of the inlet air duct 111; or the return air duct 112 may include two sections, one of which is fully surrounded on the outside of the inlet air duct 111, and the other section is partially surrounded on one side of the inlet air duct 111. On the one hand, the space outside the inlet air duct 111 can be fully utilized; on the other hand, it can ensure that the return air duct 112 has a sufficiently large flow area, reducing the resistance of airflow during the return process, thereby ensuring the cleaning effect of the cleaning device 100 in self-cleaning mode.

[0078] For example, the air inlet duct 111 can be a duct with a circular cross-section, and the return air duct 112 is arranged in a roughly "U" shaped cross-section on the outside of the air inlet duct 111. This makes the structure of the main body 10 more compact and ensures that the return air duct 112 has a sufficiently large flow area, reducing the resistance of the airflow during the return process.

[0079] Optionally, the air inlet duct 111 includes an air inlet section and an air outlet section that are interconnected. The air inlet section is configured to connect to the suction head, and the air outlet section is configured to connect to the dust cup assembly 20. The return air duct 112 includes a first section and a second section that are interconnected. The first section surrounds the side of the air outlet section away from the dust cup assembly 20, and the second section surrounds the outside of the air inlet section. The end of the air outlet section may be provided with a dust cup interface for docking with the dust cup assembly 20, and the end of the second section may be connected to a connector for docking with the base station 200. The connector may be located on the side of the air inlet duct 111 near the dust cup assembly 20. The dust cup interface of the air inlet duct 111 and the connector may be arranged opposite to each other along the axial direction of the dust cup assembly 20. Therefore, by placing the second section outside the air inlet section and the first section surrounding the side of the air outlet section away from the dust cup assembly 20, the space outside the air inlet duct 111 can be fully utilized. On the other hand, it is convenient to set a second connector 132 for docking with the base station 200 between the air inlet duct 111 and the dust cup assembly 20, thereby optimizing the layout of the cleaning equipment 100, improving space utilization, and making the structure of the cleaning equipment 100 more compact.

The cover 116 can protect the first pipe body 113, the second pipe body 114 and the transmission assembly 12, improve the structural strength and stability of the cleaning equipment 100, and by integrating the air inlet duct 111, the return air duct 112 and the transmission assembly 12 on one side of the dust cup assembly 20, the structure of the cleaning equipment 100 can be made more compact.

[0082] Combination Figure 8 and Figure 9 Furthermore, the main body 10 also includes a first connector 131, which is distributed along the axis of the connecting pipe 11 and connected to the air inlet duct 111. For example, the cleaning device 100 may include multiple suction heads, which are detachably connected to the first connector 131 to facilitate the replacement of different suction heads according to different usage needs. The first connector 131 is connected to the air inlet duct 111, and the dust-laden airflow drawn in by the suction head enters the dust cup assembly 20 through the air inlet duct 111.

[0083] Combination Figure 8 and Figure 9 The main body 10 also includes a second connector 132, which is disposed on the side of the connecting pipe 11 and located between the connecting pipe 11 and the dust cup assembly 20. The second connector 132 communicates with the return air duct 112. Exemplarily, combined with... Figure 11 The base station 200 may be provided with a secondary interface 242, and the second connector 132 may be connected to the secondary interface 242 of the base station 200 to facilitate the return of airflow in the base station 200. The second connector 132 is located between the connecting pipe 11 and the dust cup assembly 20, which can prevent the user from affecting the second connector 132 during the use of the cleaning equipment 100.

[0084] In addition, to ensure the airtightness of the second connector 132 and the auxiliary interface 242, a sealing element can be provided on the second connector 132. The second connector 132 is located between the dust cup assembly 20 and the connecting pipe 11, which can prevent the user from affecting the sealing element during the use of the cleaning equipment 100 and ensure the sealing performance after the cleaning equipment 100 is connected to the base station 200.

[0085] Combination Figure 9In some embodiments of this utility model, the connecting pipe 11 further includes a transition pipe 115. One end of the transition pipe 115 is connected to the second pipe body 114, and the other end is connected to the air duct switching component 40, for communicating with the return air duct 112 and the air duct switching component 40. Specifically, the return air duct 112 may include a first part and a second part that are connected. The first part is located between the first pipe body 113 and the second pipe body 114, and the second part is located inside the transition pipe 115. The transition pipe 115 is connected to the second pipe body 114 and the air duct switching component 40 respectively, which facilitates the connection between the return air duct 112 and the air duct switching component 40, making the structure of the cleaning equipment 100 more compact and convenient for the installation of the cleaning equipment 100.

[0086] In the aforementioned embodiment where the connecting pipe 11 includes a cover 116, the cover 116 can cover or be disposed on the outside of the adapter pipe 115, so as to protect the adapter pipe 115 and improve the connection stability between the adapter pipe 115 and the air duct switching component 40 and the connecting pipe 11.

[0087] Combination Figure 1 and Figure 2 The cleaning device 100 according to the second aspect of the present invention includes: a main body 10, the main body 10 including an air inlet duct 111 and a return air duct 112 for connecting to a base station 200.

[0088] The cleaning device 100 also includes a dust cup assembly 20, which is configured to filter the airflow entering through the air inlet duct 111. For example, the dust cup assembly 20 may contain a filter. When the cleaning device 100 is in operation, dust-laden airflow enters the dust cup assembly 20 from the air inlet duct 111. The filter can separate and filter the dirty air entering the dust cup assembly 20, and the dust and impurities filtered out are collected in the dust storage chamber of the dust cup assembly 20.

[0089] The cleaning device 100 also includes a suction device 30, which provides negative pressure. Under this negative pressure, the cleaning device 100 can suck dust, hair, and other contaminants from the working surface into the dust cup assembly 20. Furthermore, in self-cleaning mode, the cleaning device 100 can generate negative pressure in the base station 200. This means the base station 200 does not require a motor; by using the suction device 30, negative pressure is introduced into the base station 200, which cleans the dust cup assembly 20, simplifying the structure of the base station 200 and reducing noise during operation.

[0090] Combination Figure 2 and Figure 5The cleaning device 100 also includes an air duct switching assembly 40, which includes a switching body 41 and a sealing switching element 42. The switching body 41 has a first interface 412 connecting to the dust cup assembly 20, a second interface 413 connecting to the return air duct 112, and a third interface 414 connecting to the suction device 30. The sealing switching element 42 is movable to selectively block the first interface 412 and the second interface 413, thereby controlling the suction device 30 to selectively connect to the dust cup assembly 20 and the return air duct 112. For example, in the working mode, the sealing switching element 42 blocks the second interface 413 to control the suction device 30 to connect to the dust cup assembly 20; in the self-cleaning mode, the sealing switching element 42 blocks the first interface 412 to control the suction device 30 to connect to the return air duct 112. By setting the switching body 41 and the sealing switching element 42 to cooperate, the structure of the air duct switching assembly 40 is simplified, making it easier for the cleaning device 100 to switch the air duct in different modes. In addition, by providing a return air duct 112 and an air duct switching component 40 in the main body 10, it is convenient to introduce negative pressure into the base station 200 by means of the suction device 30 of the cleaning equipment 100. No motor needs to be installed on the base station 200, and self-cleaning of the cleaning equipment 100 can be achieved.

[0091] Combination Figure 5 and Figure 10 The first interface 412 and / or the second interface 413 are provided with a partition rib 415. The partition rib 415 can reduce the deformation of the sealing switching element 42, ensure airtightness, reduce the scratching between the sealing switching element 42 and the interface edge, improve the switching smoothness, reduce switching resistance, reduce the wear of the sealing switching element 42, and improve its service life and long-term stability. Specifically, the first interface 412 may be provided with a partition rib 415, or the second interface 413 may be provided with a partition rib 415, or both the first interface 412 and the second interface 413 may be provided with partition ribs 415.

[0092] For example, the sealing switching member 42 may be made of rubber; or, the sealing switching member 42 may include a rubber seal and a support structure, wherein the support structure is stacked and connected with the rubber seal, and is able to support the rubber seal to stably block the first interface 412 and the second interface 413.

[0093] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the switching body 41 has an airflow conversion chamber 411, and a sealing switching member 42 is rotatably connected to the switching body 41. The first interface 412 and the second interface 413 are distributed on the side wall of the airflow conversion chamber 411 around the rotation axis of the sealing switching member 42. The position of the switching body 41 is relatively fixed, and the air duct can be switched by rotating the sealing switching member 42, making the structure of the air duct switching assembly 40 more compact and avoiding occupying too much space in the cleaning equipment 100.

[0094] Combination Figure 5 In some embodiments, the sealing switching element 42 is disposed within the airflow conversion cavity 411, and the sealing switching element 42 extends around the rotation axis of the sealing switching element 42. For example, Figure 5 and Figure 10 As shown, the rotation axis of the sealing switching component 42 is B. For example, the sealing switching component 42 can be set in an arc shape. The position of the switching body 41 is relatively fixed. When the sealing switching component 42 rotates around the rotation axis B, it can block the first interface 412 or the second interface 413. That is to say, the air duct can be switched by rotating the sealing switching component 42, which facilitates the switching of the air duct of the air duct switching component 40 and makes the structure of the air duct switching component 40 compact.

[0095] Combination Figure 10 In some embodiments of this utility model, the dividing rib 415 includes a first rib 4151 disposed in the first interface 412. The first rib 4151 extends along the rotation axis around the sealing switching member 42. The first rib 4151 can reduce the deformation of the sealing switching member 42, so as to ensure that the sealing switching member 42 can stably block the first interface 412, ensuring airtightness. When the sealing switching member 42 rotates, it can reduce the scraping with the edge of the first interface 412, improve the switching smoothness, reduce the switching resistance, reduce the wear of the sealing switching member 42, improve the service life and the stability of long-term use.

[0096] Combination Figure 10 In some embodiments of this utility model, the separating baffle 415 includes a second baffle 4152 disposed within the second interface 413, the second baffle 4152 extending along the rotation axis surrounding the sealing switching member 42. The second baffle 4152 can reduce the deformation of the sealing switching member 42, ensuring that the sealing switching member 42 can stably block the second interface 413, ensuring airtightness, and reducing scratching with the edge of the second interface 413 when the sealing switching member 42 rotates, improving the smoothness of switching, reducing switching resistance, reducing wear of the sealing switching member 42, improving service life and stability during long-term use.

[0097] In some embodiments, the partition rib 415 includes at least two first ribs 4151 disposed in the first interface 412. The at least two first ribs 4151 are distributed along a direction parallel to the rotation axis of the sealing switching member 42. The cooperation of the at least two first ribs 4151 can further reduce the deformation of the sealing switching member 42. When the sealing switching member 42 rotates, it can effectively reduce the scraping with the edge of the first interface 412, improve the rotation smoothness of the sealing switching member 42, and improve the service life and reliability of the air duct switching assembly 40.

[0098] In some embodiments, the partition rib 415 includes at least two second ribs 4152 disposed within the second interface 413, and the at least two second ribs 4152 are distributed along a direction parallel to the rotation axis of the sealing switching member 42. The cooperation of the at least two second ribs 4152 can further reduce the deformation of the sealing switching member 42, and when the sealing switching member 42 rotates, it can effectively reduce the scraping with the edge of the second interface 413, improve the smoothness of the rotation of the sealing switching member 42, and improve the service life and reliability of the air duct switching assembly 40.

[0099] In some embodiments, the first interface 412, the second interface 413 and the third interface 414 are distributed around the rotation axis of the sealing switching member 42, making the structure of the air duct switching assembly 40 more compact, and facilitating the connection of the air duct switching assembly 40 to the dust cup assembly 20, the suction device 30 and the return air duct 112, thus making the structure of the cleaning equipment 100 more compact.

[0100] Combination Figure 5 In some embodiments, the axis of the first interface 412 and the axis of the second interface 413 are perpendicular, as shown in the figure. The axis of the first interface 412 is C, and the axis of the second interface 413 is D. The axis C and the axis D may have an angle of 90°, which optimizes the arrangement of the air duct and facilitates the switching of the air duct by blocking the first interface 412 or the second interface during rotation. It also makes the structure of the air duct switching assembly 40 more compact. The air duct switching assembly 40 connects the dust cup assembly 20 and the return air duct 112, making the structure of the cleaning equipment 100 more compact.

[0101] Combination Figure 2 , Figure 5 and Figure 10 In some embodiments, the suction device 30 includes a motor housing 31 connected to a third interface 414, and the motor housing 31 is integrally formed with the switching body 41. The motor housing 31 supports and fixes the motor. By making the switching body 41 and the motor housing 31 integrally formed, it is easier for the suction device 30 to connect to the ventilation duct switching assembly 40, and the number of parts is reduced, the structural strength is improved, and the structure of the cleaning equipment 100 is more compact.

[0102] In some embodiments, the cleaning device 100 has a working mode and a self-cleaning mode; wherein, in the working mode, the air duct switching component 40 connects the suction device 30 and the dust cup assembly 20; and in the self-cleaning mode, the air duct switching component 40 connects the suction device 30 and the return air duct 112. Figure 2Specifically, in the working mode, the air duct switching component 40 connects the suction device 30 to the dust cup assembly 20. The suction head draws dust, hair, debris, and other contaminants from the work surface into the dust cup assembly 20 through the air inlet duct 111. The dust cup assembly 20 is in a closed state and filters the airflow. The clean airflow filtered by the dust cup assembly 20 is then discharged outside the cleaning equipment 100 via the suction device 30. Figure 12 After the cleaning equipment 100 completes the cleaning work, it can be connected to the base station 200. In the self-cleaning mode, the air duct switching component 40 connects the suction device 30 to the return air duct 112. The dust cup component 20 can be connected to the base station 200, and the base station 200 is connected to the return air duct 112. Under the action of the suction device 30, a negative pressure is generated in the base station 200, so that the dust, debris, hair and other dirt in the dust cup component 20 are collected in the base station 200. The airflow in the base station 200 flows back to the suction device 30 through the return air duct 112 and is discharged to the outside of the cleaning equipment 100 through the suction device 30.

[0103] Combination Figure 1 and Figure 2 In some embodiments, the main body 10 includes a connecting pipe 11, which has an air inlet duct 111 for connecting to the suction head. At least a portion of a return air duct 112 is disposed in the connecting pipe 11. The air duct switching assembly 40 is disposed in the main body 10. The fact that at least a portion of the return air duct 112 is disposed in the connecting pipe 11 allows for full utilization of the space within the connecting pipe 11, preventing significant changes in the main body's appearance due to the return air duct 112, such as protrusions in corresponding parts or increased main body size, thus simplifying the main body's structure. Combined with... Figure 11 and Figure 12 The present invention also proposes a cleaning system, including: a base station 200 and the aforementioned cleaning device 100. The base station 200 has a dust collection duct 210 and a bypass duct 220 that are interconnected. The cleaning device 100 is detachably connected to the base station 200. In the self-cleaning mode, the air inlet duct 111 is connected to the dust cup assembly 20, and the dust cup assembly 20 is connected to the dust collection duct 210, and the bypass duct 220 is connected to the return air duct 112.

[0104] For example, the base station 200 may be provided with a main interface 241, which is connected to the dust collection duct 210 and is detachably connected to the dust cup assembly 20. In the self-cleaning mode, the air duct switching component 40 connects the suction device 30 to the return air duct 112. The suction device 30 operates, and a negative pressure is generated inside the base station 200, so that dust, debris, hair and other dirt in the dust cup assembly 20 are collected into the dust bag 243 of the base station 200. The airflow inside the base station 200 flows back to the return air duct 112 of the cleaning device 100 through the bypass air duct 220, and finally is discharged outside the cleaning device 100 through the suction device 30. By installing a bypass ventilation duct 220 on the base station 200 and a return air duct 112 on the cleaning device 100, the base station 200 does not require a motor. Negative pressure is introduced into the base station 200 via the suction device 30 of the cleaning device 100, creating negative pressure within the base station 200. This negative pressure cleans and collects dirt from the dust cup of the cleaning device 100, simplifying the structure of the base station 200 and reducing noise during operation. Figure 12 The arrows indicate the direction of airflow in the self-cleaning mode of the cleaning device 100. The airflow flows along the air inlet duct 111, dust cup assembly 20, dust collection duct 210, bypass duct 220, return duct 112 and suction device 30.
