Description

Technical Field

[0001] The present application belongs to the technical field of cleaning equipment, and specifically relates to a dust collection station for storing vacuum cleaners. Background Art

[0002] Existing handheld vacuum cleaners are equipped with dust cups, but the dust cups have limited dust storage space, and the dust cups need to be cleaned regularly during use. To achieve automatic cleaning and storage of the handheld vacuum cleaners, a dust collection station that can receive dirt in the dust cups is usually provided.

[0003] The prior art discloses a recycling device, including a vacuum device connection device, an air duct, a dust collecting device and a motor system. The vacuum device connection device is used to connect with the vacuum device and open and close the dust cup bottom cover of the vacuum device. The dust collecting device is used to collect the contents sucked by the dust cup. The motor system is used to provide vacuuming power for the recycling device. A floor brush holder is provided at the bottom of the recycling device, and the floor brush holder is used to place the floor brush of the vacuum device. The motor system is also provided at the bottom of the recycling device. The motor system includes a main motor and a main motor cover. The side of the main motor cover is provided with a motor air outlet. When the recycling device collects dust, the motor system is connected to the dust cup through the dust collecting device, and the dirt in the dust cup is sucked into the dust collecting device under the action of gravity or suction force. The airflow of the motor system causes the cavity formed at the connection point of the vacuum device connection device and the vacuum device to form a negative pressure zone, and the moving dust gas enters the dust collecting device and is discharged from the motor air outlet. In order to better achieve dust and gas separation and prevent dirt from leaving the motor air outlet, the dust collecting station usually provides a replaceable filter module at the motor air outlet. However, the filtering effect of the filter module decreases with the use time. During the air outlet process, some particles will flow to the air outlet with the wind and be discharged from the air outlet, which will still cause secondary pollution. Utility Model Content

[0004] The present application provides a dust collecting station for storing vacuum cleaners, so as to solve the technical problem that the exhaust port of the existing dust collecting station still carries dirt during the exhaust process, causing secondary pollution.

[0005] The technical solution adopted in this application is:

[0006] A dust collecting station for storing a vacuum cleaner, comprising a dust collecting chamber for collecting dirt in the vacuum cleaner, a dust collecting motor and an exhaust port, the vacuum cleaner comprising a body with a dust cup and a floor brush with a cleaning member, the body and the floor brush being pivotally connected, and when the vacuum cleaner is stored in the dust collecting station, a projection of the exhaust port in the exhaust direction is at least partially located on the floor brush.

[0007] The dust collection station for storing a vacuum cleaner described in the present application also includes the following additional technical features:

[0008] The floor brush further comprises a front cover and a dust suction port. When the vacuum cleaner is stored in the dust collection station, the front cover or the dust suction port is arranged opposite to the exhaust port.

[0009] One of the floor brush and the body is provided with a limiting portion, and the other is provided with a matching portion. The limiting portion and the matching portion stop cooperate to limit the angle between the floor brush and the vertical direction to an angle α when the vacuum cleaner is placed in the dust collection station.

[0010] When the vacuum cleaner is stored in the dust collecting station, there is an angle α between the plane where the front cover is located or the bottom surface of the floor brush and the vertical direction, and the angle α satisfies: α≤45°.

[0011] When the vacuum cleaner is placed in the dust collection station, the cleaning member and the dust collection motor can operate synchronously to guide the fluid discharged from the exhaust port to flow toward the dust suction port of the floor brush.

[0012] The center of the floor brush faces the central area of ​​the air outlet.

[0013] A receiving cavity for receiving the floor brush is provided at the lower part of the dust collecting station, the receiving cavity comprises a side wall and a top wall, and the floor brush is at least partially arranged on the projection of the top wall in the vertical direction.

[0014] The air outlet is arranged on the side wall, and the top wall is an arc segment connected to the side wall. The arc segment is recessed inward to form an escape space for evading the pivot structure between the floor brush and the body.

[0015] The dust collecting station is provided with a handle at the air outlet, the handle and the dust collecting station are detachably mounted, and the projection of the floor brush in the vertical direction does not overlap with the handle.

[0016] The dust collecting station is provided with a avoidance cavity extending vertically, and a partial area of ​​the upper part of the floor brush is accommodated in the avoidance cavity.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The dust collecting station in the present application can be used to store vacuum cleaners, solving the problem of unstable and messy placement of vacuum cleaners. When the vacuum cleaner is stored in the dust collecting station, the floor brush of the vacuum cleaner is located on the exhaust side of the exhaust port of the dust collecting station, and the projection of the exhaust port in the exhaust direction is at least partially located on the floor brush, so that during the operation of the dust collecting station, on the one hand, the suction force at the dust suction port of the floor brush can be used to suck the wind and dirt discharged from the exhaust port into the dust cup of the vacuum cleaner again, and then enter the dust collecting chamber of the dust collecting station, forming an exhaust cycle, which greatly reduces the probability of dirt discharged from the exhaust port being discharged into the air. On the other hand, the relative arrangement of the exhaust port and the floor brush enables that when the fluid discharged from the exhaust port carries dirt such as particulate matter, the dirt can hit the outer surface of the floor brush with the wind, and part of the dirt that has not entered the dust suction port of the floor brush changes its movement direction due to the collision, reducing the diffusion range of the dirt, thereby reducing the cleaning burden of the user.

[0019] 2. As a preferred embodiment of the present application, when the vacuum cleaner is stored in the dust collecting station, the front cover of the floor brush is arranged opposite to the exhaust port, or the dust suction port of the floor brush is arranged opposite to the exhaust port. This arrangement helps to optimize the fluid flow path, make the air flow smoother, and reduce energy loss. During the operation of the dust collecting station, the air flow generated during the dust collection process can be effectively sucked in through the dust suction port of the floor brush and guided into the dust collecting chamber, so as to achieve exhaust circulation and reduce the secondary pollution of the surrounding environment by dirt during the exhaust process. Moreover, the relative position relationship between the exhaust port and the front cover or the dust suction port of the floor brush helps to ensure that after the vacuum cleaner is stored in the dust collecting station, the two maintain a relatively harmonious storage posture. The floor brush at least partially blocks the exhaust port, which greatly reduces the probability of impurities in the external environment entering the dust collecting station through the exhaust port when the dust collecting station is not working, and reduces the risk of blockage of the exhaust port, thereby forming an effective protection for the dust collecting station.

[0020] 3. As a preferred embodiment of the present application, the floor brush and the body cooperate with each other through the stopper of the limiting part and the matching part, so as to limit the angle between the floor brush and the vertical direction to an angle α when the vacuum cleaner is placed in the dust collecting station. On the one hand, by limiting the floor brush to the angle α, the space occupied by the vacuum cleaner when stored can be made more compact, saving space and improving the storage efficiency of the dust collecting station. On the other hand, it can ensure the position accuracy of the vacuum cleaner when stored, and improve the stability of the two after the vacuum cleaner is stored in the dust collecting station, so as to avoid accidental collision or unstable center of gravity due to improper position, thereby causing the dust collecting station to overturn. Furthermore, by limiting the angle between the floor brush and the vertical direction, the floor brush and the exhaust port can be maintained at a better angle, thereby improving the suction or dust blocking effect of the floor brush on the exhaust port, thereby improving the cleaning effect.

[0021] 4. As a preferred embodiment of the present application, when the vacuum cleaner is stored in the dust collection station, the cleaning parts of the floor brush and the dust collection motor of the dust collection station operate synchronously. The operation of the cleaning parts can form drainage for the airflow near the exhaust port, thereby guiding the fluid discharged from the exhaust port to flow toward the dust suction port of the floor brush, improving the dust suction efficiency of the dust suction port of the floor brush, thereby improving the cleaning efficiency. Moreover, the drainage effect of the running cleaning parts on the airflow can reduce the turbulence phenomenon caused by the airflow hitting the floor brush. On the one hand, it can make the air flow more orderly, reduce the air flow resistance, and improve the dust collection efficiency. On the other hand, it can reduce the noise caused by the air flow and improve the user experience.

[0022] 5. As a preferred embodiment of the present application, the center of the floor brush faces the center area of ​​the exhaust port. The center-to-center layout design can accurately guide the airflow, reduce ineffective air flow, form a shorter and more direct airflow path, reduce energy loss, and improve exhaust circulation efficiency. Moreover, this embodiment can optimize the airflow path and reduce the noise caused by airflow turbulence. In addition, the relative position relationship between the floor brush and the exhaust port is arranged with strong symmetry, which makes the overall appearance of the vacuum cleaner more neat and coordinated when it is stored in the dust collection station, and improves the appearance quality of the whole product.

[0023] 6. As a preferred embodiment of the present application, a holding cavity for accommodating a floor brush is provided at the bottom of the dust collecting station. At least part of the floor brush is accommodated in the holding cavity, which can make full use of the vertical and horizontal space of the dust collecting station, reduce or even avoid the arrangement of the floor brush protruding from the dust collecting station, thereby reducing the probability of the whole machine tipping over due to accidental touching of the floor brush in the storage state, and can reduce the overall space occupancy rate of the two after the vacuum cleaner is stored in the dust collecting station, saving the space requirement for storing both. The holding cavity includes side walls and a top wall, and the floor brush is at least partially arranged on the vertical projection of the top wall. The structural design of the top wall can be fully utilized to accommodate a part of the floor brush area, thereby both rationalizing the layout of the structure of the dust collecting station and storing the floor brush, so that after the vacuum cleaner is stored, the whole machine is more compact and reduces space occupancy.

[0043] like Figures 4 to 8 As shown, a dust collecting station for storing a vacuum cleaner includes a dust collecting chamber 15 for collecting dirt in the vacuum cleaner 2, a dust collecting motor 16 and an exhaust port 11. The vacuum cleaner 2 includes a body 22 with a dust cup 23 and a floor brush 21 with a cleaning member 213. The body 22 and the floor brush 21 are pivotally connected. When the vacuum cleaner 2 is stored in the dust collecting station 1, the projection of the exhaust port 11 in the exhaust direction is at least partially located on the floor brush 21.

[0044] After the vacuum cleaner 2 finishes working, the vacuum cleaner 2 is stored on the dust collecting station 1 to achieve storage of the vacuum cleaner 2, solving the problem of the vacuum cleaner 2 being placed unsteadily and in a mess. The dust cup 23 of the vacuum cleaner 2 is opened by running the dust collecting motor 16, or the dust cup 23 is unlocked and in an open state when the vacuum cleaner 2 is installed on the dust collecting station 1. The running dust collecting motor 16 collects the dirt in the dust cup 23 into the dust collecting chamber 15 through the dust collecting flow channel provided in the dust collecting station 1, avoiding the problem of dirt scattering caused by dumping the dust cup 23, and facilitating the centralized collection and treatment of the dirt.

[0045] A cyclone duct is provided in the dust collecting chamber 15 to separate the flowing gas from dust and gas. The separated gas enters the dust collecting motor 16 and is filtered by the filter element provided at the exhaust port before flowing out from the exhaust port 11. Since the suction port 212 of the floor brush 21 is connected to the dust cup 23 through the suction flow channel in the body 22, the vacuum cleaner 2 is stored in the dust collecting station 1 and the dust cup 23 is in a connected state with the dust collecting chamber 15. When the dust collecting motor 16 is operated, air flow from the suction port 212 of the floor brush 21 to the exhaust port 11 of the dust collecting station 1 can be formed through the interconnected suction flow channel, dust collecting flow channel and exhaust flow channel. In the present application, when the vacuum cleaner 2 is stored in the dust collecting station 1, the floor brush 21 of the vacuum cleaner 2 is located on the exhaust side of the exhaust port 11 of the dust collecting station 1, and the projection of the exhaust port 11 in the exhaust direction is at least partially located on the floor brush 21, so that when the fluid discharged from the exhaust port 11 carries particulate matter and other dirt, the dirt can be hit by the wind to the outer surface of the floor brush 21, and some of the dirt that has not entered the dust suction port 212 of the floor brush 21 changes its movement direction due to the impact, thereby reducing the diffusion range of the dirt, thereby reducing the cleaning burden of the user.

[0046] On the other hand, when the dust collecting motor 16 is working, negative pressure is formed in the suction flow channel connected to the dust collecting station 1, so that the suction force at the dust suction port 212 of the floor brush 21 can be used to suck the wind and dirt discharged from the exhaust port 11 into the dust cup 23 of the vacuum cleaner 2 again, and then enter the dust collecting chamber 15 of the dust collecting station 1, forming an exhaust circulation, which greatly reduces the probability of dirt discharged from the exhaust port 11 being discharged into the air.

[0047] like Figure 4 , Figure 6 and Figure 8 As shown, the floor brush 21 further includes a front cover 211 and a dust suction port 212. When the vacuum cleaner 2 is stored in the dust collection station 1, the specific positional relationship between the floor brush 21 and the exhaust port 11 can be any one of the following embodiments:

[0048] Implementation method 1: Figures 4 to 7As shown, the front cover 211 is arranged opposite to the exhaust port 11. This helps to ensure that after the vacuum cleaner 2 is stored in the dust collecting station 1, the floor brush 21 blocks at least part of the exhaust port 11. First, the probability of impurities in the external environment entering the dust collecting station 1 through the exhaust port 11 when the dust collecting station 1 is not in operation is greatly reduced, and the risk of the exhaust port 11 being blocked is reduced, thereby forming an effective protection for the exhaust port of the dust collecting station 1. Secondly, during the air discharge from the exhaust port 11, at least part of the airflow will hit the front cover 211, and the airflow will be turned to convert the horizontally blown wind into a downward movement, so as to prevent the wind blown out of the exhaust port 11 from disturbing the dirt in the environment. Finally, the airflow blown out of the exhaust port 11 may be mixed with some particles. After hitting the front cover 211, the blown particles will settle between the floor brush 21 and the dust collecting station 1 to prevent the dust from further spreading into the environment, making it convenient for users to clean.

[0049] Furthermore, the floor brush 21 at least partially blocks the exhaust port 11, so that the exhaust port 11 is close to the dust suction port 212 located on the floor brush 21. When the dust collecting motor 16 is working, it is connected with the body 22 through the dust collecting chamber 15, so that a negative pressure is formed at the dust suction port 212, and the airflow flowing out of the exhaust port 11 re-enters the dust suction port 212, forming an air path circulation. The floor brush 21 that has completed the floor cleaning may be mixed with some dirt. In the process of the wind at the exhaust port 11 entering the dust suction port 212, the floating dust remaining on the surface of the floor brush 21 is brought back into the body 22 and finally stored in the dust collecting chamber 15. This embodiment realizes the exhaust circulation, reduces the secondary pollution of the surrounding environment by dirt during the exhaust process, and at the same time realizes the simple cleaning of the floor brush 21 to avoid the scattering of floating dust on the floor brush 21.

[0050] Implementation method 2: Figure 8 As shown, the dust suction port 212 is arranged opposite to the exhaust port 11. In addition to the advantages of the above-mentioned embodiment 1, the second embodiment has the advantages that the dust suction port 212 is opposite to the exhaust port 11, so that the fluid discharged from the exhaust port 11 can be directly sucked into the dust suction port 212, further shortening the flow path of the fluid, improving the exhaust recovery efficiency, and further reducing the probability of dirt falling to the periphery of the dust collection station 1.

[0051] As a preferred embodiment of this implementation, Fig. 9 and Fig.10As shown, one of the floor brush 21 and the body 22 is provided with a limiting portion, and the other of the two is provided with a matching portion. The limiting portion and the matching portion stopper cooperate to limit the angle between the floor brush 21 and the vertical direction to an angle α when the vacuum cleaner 2 is placed in the dust collecting station 1. On the one hand, by limiting the floor brush 21 to an angle α, the space occupied by the vacuum cleaner 2 when stored can be made more compact, saving space and improving the storage efficiency of the dust collecting station 1. On the other hand, it can ensure the position accuracy of the vacuum cleaner 2 when stored, improve the stability of the two after the vacuum cleaner 2 is stored in the dust collecting station 1, and avoid accidental collision or unstable center of gravity due to improper position, thereby causing the dust collecting station 1 to overturn. Furthermore, by limiting the angle between the floor brush 21 and the vertical direction, the floor brush 21 and the exhaust port 11 can be kept at a better angle, improving the suction effect of the floor brush 21 on the exhaust at the exhaust port 11, thereby improving the cleaning effect.

[0052] In a specific example, Fig. 9 and Fig.10 As shown, the floor brush 21 includes a shell, which is rotatably connected to the body 22 via a rotating shaft. The body 22 is provided with a positioning seat for installing the rotating shaft. The limiting portion is a limiting rib 214 provided on the shell and extending toward one side of the rotating shaft. The matching portion is a stop structure 215 provided on the positioning seat. When the floor brush 21 is rotated to a state where the limiting rib 214 abuts against the positioning seat, the floor brush 21 is restricted to a posture at an angle α with the vertical direction.

[0053] Furthermore, if Figures 6 to 8 As shown, when the vacuum cleaner 2 is stored in the dust collecting station 1, there is an angle α between the plane where the front cover 211 is located or the bottom surface of the floor brush 21 and the vertical direction, and the angle α satisfies: α≤45°.

[0054] The plane where the front cover 211 is located refers to a plane parallel to the bottom surface of the floor brush 21. The bottom surface of the floor brush 21 refers to a surface of the floor brush 21 opposite to the front cover 211, and the bottom surface and the front cover 211 are located at two opposite sides of the floor brush 21 respectively.

[0055] When the angle α is less than or equal to 45°, the airflow path between the exhaust port 11 and the front cover 211 of the floor brush 21, or the airflow path between the exhaust port 11 and the dust suction port 212 of the floor brush 21, can be further optimized so that as much airflow as possible can be re-sucked into the dust collection station 1 from the dust suction port 212. A small amount of airflow can change its flow direction when it hits the floor brush 21 and fall under the action of its own weight to accumulate in a small range, making it convenient for users to clean.

[0056] As a preferred embodiment of the present application, when the vacuum cleaner 2 is placed in the dust collection station 1, the cleaning member 213 and the dust collection motor 16 can operate synchronously to guide the fluid discharged from the exhaust port 11 to flow toward the dust suction port 212 of the floor brush 21. The operation of the cleaning member 213 can form a drainage for the airflow near the exhaust port 11, thereby guiding the fluid discharged from the exhaust port 11 to flow toward the dust suction port 212 of the floor brush 21, improving the dust suction efficiency of the dust suction port 212 of the floor brush 21, thereby improving the cleaning efficiency. Moreover, the drainage effect of the running cleaning member 213 on the airflow can reduce the turbulence phenomenon caused by the airflow hitting the floor brush 21. On the one hand, it can make the air flow more orderly, reduce the air flow resistance, and improve the dust collection efficiency. On the other hand, it can reduce the noise caused by the air flow and improve the user experience.

[0057] The following is an example of the front cover 211 and the exhaust port 11 being arranged relative to each other to further explain this embodiment. Figure 7 As shown, when the vacuum cleaner 2 is stored in the dust collecting station 1 and the dust collecting motor 16 is running, the cleaning member 213 also operates synchronously. During this process, the airflow is discharged from the exhaust port 11 and blown to the front cover 211 of the floor brush 21. The airflow carrying dirt flows downward along the outer surface of the front cover 211 due to factors such as impact and deadweight. At this time, the cleaning member 213 rotates in a counterclockwise direction, which can guide the airflow below the cleaning member 213, so that the airflow carrying dirt moves toward the dust suction port 212 of the floor brush 21 under the guidance, and is sucked into the vacuum cleaner 2, and then enters the dust collecting station 1.

[0058] As a preferred embodiment of the present application, Figure 4 and Figure 5 As shown, the center of the floor brush 21 is facing the center area of ​​the exhaust port 11. The center-to-center layout design can accurately guide the airflow, reduce ineffective air flow, form a shorter and more direct airflow path, reduce energy loss, and improve the exhaust circulation efficiency. Moreover, this embodiment can optimize the airflow path and reduce the noise caused by airflow turbulence. In addition, the relative position relationship between the floor brush 21 and the exhaust port 11 is arranged with strong symmetry, so that the overall appearance of the vacuum cleaner 2 is neater and more coordinated when it is stored in the dust collection station 1, and the appearance quality of the whole product is improved. Furthermore, the dust suction port 212 is based on the central axis of the floor brush 21. The suction force of the dust suction port 212 is the largest in the middle and gradually weakens on both sides. Therefore, when the center of the floor brush 21 is facing the center area of ​​the exhaust port 11, it can cooperate with the suction force of the dust suction port 212 to increase the suction amount of the airflow discharged from the exhaust port 11 by the dust suction port 212, thereby improving the exhaust recovery efficiency.

[0059] As a preferred embodiment of this implementation, Figure 1 and Figure 3As shown, the lower part of the dust collecting station 1 is provided with a plurality of exhaust holes, and the exhaust hole 11 is an exhaust area formed by the combination of the plurality of exhaust holes. By providing a plurality of exhaust holes, on the one hand, the exhaust efficiency is further improved, and on the other hand, the probability of foreign matter entering the dust collecting station 1 through the exhaust hole 11 is reduced.

[0060] In the present application, the state of the vacuum cleaner 2 after being stored in the dust collecting station 1 can adopt any one of the following embodiments:

[0061] Embodiment 3: After the vacuum cleaner 2 is stored in the dust collecting station 1, the floor brush 21 is arranged opposite to the exhaust port 11 and is located outside the dust collecting station 1. That is, the dust collecting station 1 is not provided with a structure specifically for storing the floor brush 21, and the floor brush 21 is suspended and stored outside the dust collecting station 1.

[0062] Implementation method 4: Figure 2 , Figures 6 to 8 As shown, the lower part of the dust collecting station 1 is provided with a receiving chamber 17 for receiving a floor brush 21, and the receiving chamber 17 includes a side wall 171 and a top wall 172, and the floor brush 21 is at least partially arranged on the vertical projection of the top wall 172. Accommodating at least part of the floor brush 21 in the receiving chamber 17 can make full use of the vertical and horizontal spaces of the dust collecting station 1, reduce or even avoid the arrangement of the floor brush 21 protruding from the dust collecting station 1, thereby reducing the probability of the whole machine tipping over due to accidental contact with the floor brush 21 in the storage state, and can reduce the overall space occupancy rate of the vacuum cleaner 2 after being stored in the dust collecting station 1, saving the space requirement for storing both. The accommodating chamber 17 includes side walls 171 and a top wall 172. The floor brush 21 is at least partially arranged on the projection of the top wall 172 in the vertical direction. The structural design of the top wall 172 can be fully utilized to accommodate a partial area of ​​the floor brush 21, thereby rationalizing the layout of the structure of the dust collecting station 1 and storing the floor brush 21. After the vacuum cleaner 2 is stored, the whole machine is more compact and the space occupancy is reduced.

[0063] In one embodiment, the side wall 171 cooperates with the top wall 172 to form an inverted L-shaped structure, and the air outlet 11 is disposed on the side wall 171 .

[0064] In a preferred embodiment, Figure 2 and Figure 8 As shown, the air outlet 11 is provided on the side wall 171, and the top wall 172 is an arc segment connected to the side wall 171, and the arc segment is recessed inward to form an escape space for the pivot structure 24 between the floor brush 21 and the body 22. The top wall 172 is an arc segment, which can form the escape space and occupy relatively less internal space of the dust collecting station 1, thereby avoiding the components in the dust collecting station 1 and realizing a compact layout of the structure.

[0065] As a preferred embodiment of the present application, Figure 1 and Figure 5 As shown, the dust collecting station 1 is provided with a handle 121 at the air outlet 11, and the handle 121 is detachably mounted on the dust collecting station 1, and the projection of the floor brush 21 in the vertical direction does not overlap with the handle 121. Furthermore, the dust collecting station 1 is provided with a cover plate 12 with a grid at the air outlet 11, and the cover plate 12 divides the air outlet 11 into a plurality of air exhaust holes. By providing the cover plate 12, not only the coordination and aesthetic effect of the whole machine can be improved, but also foreign objects in the external environment can be blocked from entering the dust collecting station 1 through the air outlet 11. The handle 121 is provided on the cover plate 12, and the cover plate 12 is detachably connected to the dust collecting station 1, so as to facilitate the cleaning of the cover plate 12. The projection of the floor brush 21 in the vertical direction does not overlap with the handle 121, so that the user can easily remove the cover plate 12 without removing the vacuum cleaner 2.

[0066] As a preferred embodiment of this implementation, Figure 1 As shown, filter cotton 14 and filter HEPA 13 are also provided at the exhaust port 11. The filter cotton 14, filter HEPA 13 and cover plate 12 are arranged in sequence from the inside to the outside, so as to further filter the fluid flowing out of the dust collecting chamber 15 to the exhaust port 11, thereby reducing the probability of dirt flowing out of the exhaust port 11 with the gas.

[0067] As a preferred embodiment of the present application, Figure 1 and Figure 2 As shown, the dust collecting station 1 is provided with a avoidance chamber 18 extending vertically, and part of the upper area of ​​the floor brush 21 is accommodated in the avoidance chamber 18. By setting the avoidance chamber 18, the interference between the floor brush 21, the body 22 and the dust collecting station 1 in space can be avoided when the whole machine is stored, and the horizontal distance between the floor brush 21 and the exhaust port 11 can be further shortened, and the gas flow path between the exhaust port 11 and the dust suction port 212 can be shortened. Furthermore, the setting of the avoidance chamber 18 can also limit the floor brush 21, reducing the area of ​​the floor brush 21 exposed to the outside of the dust collecting station 1, thereby reducing the probability of the floor brush 21 being accidentally touched, and ensuring the stability of the whole machine storage.

[0068] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0069] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0070] The above is only the embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
