[0002] Cleaning devices are used to remove dust, debris, and other impurities from the air and ground. They clean the ground and air by using negative pressure generated inside the device to draw in air and impurities.

[0003] However, the structure of the cleaning device in the relevant technology is unreasonable, resulting in chaotic airflow within the cleaning device and low airflow efficiency. Summary of the Invention

[0006] This invention provides a cleaning device, which includes a housing, an air guide assembly, and a filter element. Both the air guide assembly and the filter element are installed within the housing. The air guide assembly is movably positioned around the outer periphery of the filter element along the height direction of the cleaning device. The filter element has a first channel, and a second channel is formed between the air guide assembly and the filter element. The first and second channels are not interconnected. The cleaning device has a vacuuming state and a self-cleaning state. When the cleaning device is in the vacuuming state, the air guide assembly abuts against the housing and closes the second channel, allowing airflow within the cleaning device to flow through the first channel. When the cleaning device is in the self-cleaning state, the air guide assembly detaches from the housing and opens the second channel, allowing airflow within the cleaning device to flow through both the first and second channels.

[0007] In some implementations, the air guide assembly does not have filter holes.

[0008] In some embodiments, the housing includes a shell and a mounting component. The mounting component is connected to the shell. An air guide assembly and a filter are mounted on the shell and respectively connected to the mounting component. The mounting component has a first air outlet and a second air outlet. The second air outlet surrounds the outer periphery of the first air outlet. The first air outlet is connected to a first channel. When the cleaning device is in the dust suction state, the air guide assembly abuts against the mounting component and closes the second channel. When the cleaning device is in the self-cleaning state, the air guide assembly detaches from the mounting component and opens the second channel, and the second air outlet is connected to the second channel.

[0009] In some embodiments, the air guide assembly includes an air guide and an elastic element. One end of the elastic element is connected to the mounting element, and the other end of the elastic element is connected to the air guide. When the cleaning device is in the dust suction state, the elastic element is in the extended state, and the elastic force of the elastic element is suitable for pressing the air guide against the mounting element. When the cleaning device is in the self-cleaning state, the elastic element is in the compressed state, and the air guide is detached from the mounting element.

[0010] In some embodiments, the mounting component has a mounting cavity and a guide portion, the guide portion is located in the mounting cavity, the elastic element surrounds the outer periphery of the guide portion, and the air guide is located outside the mounting cavity and spaced apart from the side wall of the mounting component.

[0011] In some embodiments, the mounting component is provided with a first limiting part and a second limiting part, which are distributed along the height direction. When the cleaning device is in the dust suction state, the air guide is pressed against the first limiting part; when the cleaning device is in the self-cleaning state, the air guide is pressed against the second limiting part.

[0012] In some embodiments, the first limiting portion includes a first limiting sub-portion and a second limiting sub-portion, the first limiting sub-portion and the second limiting sub-portion are respectively located on both sides of the guide portion in the radial direction, and the first limiting sub-portion is disposed closer to the filter element than the second limiting sub-portion.

[0013] In some embodiments, the air guide assembly includes an air guide element having a flow guide portion located at the end of the air guide element away from the mounting element.

[0014] In some embodiments, the air guide is further provided with a flow-guiding reinforcement section, which is located on the side of the air guide away from the filter element, and the flow guide section avoids the flow-guiding reinforcement section.

[0015] In some embodiments, the housing is further provided with a reinforcing part, which is connected to the mounting component and surrounds the outer periphery of the first air vent, and the reinforcing part is located between the first air vent and the second air vent.

[0016] The cleaning device provided in this invention comprises an air guide assembly and a filter element both installed within a housing. The air guide assembly is movably positioned around the outer periphery of the filter element along the height direction of the cleaning device. The filter element has a first channel, and a second channel is formed between the air guide assembly and the filter element. The first and second channels are not interconnected. The cleaning device has a vacuuming state and a self-cleaning state. When the cleaning device is in the vacuuming state, the air guide assembly abuts against the housing and closes the second channel, allowing airflow within the cleaning device to flow through the first channel. When the cleaning device is in the self-cleaning state, the air guide assembly detaches from the housing and opens the second channel, allowing airflow within the cleaning device to flow through both the first and second channels. Thus, the cleaning device can adjust the position of the air guide assembly according to actual needs for vacuuming or self-cleaning. The air guide assembly can open or close the second channel according to the corresponding state of the cleaning device, allowing airflow within the cleaning device to flow in a predetermined direction, which helps optimize the airflow path, reduce turbulence and resistance, and improve airflow efficiency.

[0028] To enable those skilled in the art to better understand the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the embodiments of the present invention.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Please see Figures 1 to 5 This invention provides a cleaning device 100, which can be a vacuum cleaner or other cleaning device. The cleaning device 100 includes a housing 11, an air guide assembly 12, and a filter element 13. Both the air guide assembly 12 and the filter element 13 are installed in the housing 11. The air guide assembly 12 is movably arranged around the outer periphery of the filter element 13 along the height direction Y of the cleaning device 100. The filter element 13 has a first channel 131, and a second channel 132 is formed between the air guide assembly 12 and the filter element 13. The first channel 131 and the second channel 132 are not interconnected. The cleaning device 100 has a dust-collecting state and a self-cleaning state. When the cleaning device 100 is in the dust-collecting state, the air guide assembly 12 abuts against the housing 11 and closes the second channel 132, and the airflow in the cleaning device 100 flows through the first channel 131. When the cleaning device 100 is in the self-cleaning state, the air guide assembly 12 detaches from the housing 11 and opens the second channel 132, and the airflow in the cleaning device 100 flows through the first channel 131 and the second channel 132.

[0031] Thus, the cleaning device 100 can adjust the position of the air guide component 12 according to actual needs to perform dust suction or self-cleaning. The air guide component 12 can open or close the second channel 132 according to the corresponding state of the cleaning device 100, so that the airflow in the cleaning device 100 can flow in a predetermined direction according to the corresponding state of the cleaning device 100, which helps to optimize the airflow path, reduce turbulence and resistance, and improve the airflow efficiency.

[0032] For example, such as Figure 2 and Figure 3As shown, when the cleaning device 100 is working, the air guide assembly 12 moves upward along the height direction Y of the cleaning device 100 and abuts against the outer casing 11, and the second channel 132 is closed. At this time, the negative pressure airflow inside the cleaning device 100 can only flow upward through the first channel 131. This helps to optimize the airflow path when the cleaning device is in the dust-collecting state, helps to reduce turbulence and resistance, helps to improve the airflow efficiency, and also helps to ensure that the airflow can pass through the filter element 13 for filtration, thus improving the filtration effect of the airflow.

[0033] When the cleaning device 100 needs to self-clean, such as Figure 4 and Figure 5 As shown, the air guide assembly 12 moves downward along the height direction Y of the cleaning device 100 and detaches from the housing 11, opening the second channel 132. At this time, the positive pressure airflow inside the cleaning device 100 can flow downward through the first channel 131 and the second channel 132. This helps optimize the airflow path of the cleaning device 100 in its self-cleaning state, reduces turbulence and resistance, and improves airflow efficiency. The airflow through the first channel 131 and the second channel 132 facilitates the airflow through the inner and outer sides of the filter element 13, cleaning the inner and outer sides of the filter element 13 and the space between the air guide assembly 12 and the housing 11, thus increasing the cleaning area and cleaning zone of the cleaning device 100.

[0034] In some embodiments, the air guide assembly 12 does not have filter holes. This helps to reduce the possibility of airflow escaping from the filter holes, helps the airflow to flow better in the intended direction, and also helps to reduce airflow resistance. This helps to improve the suction power of the cleaning device 100 in the dust-collecting state, so as to more effectively collect dust and debris. It also helps to improve the airflow of the cleaning device 100 in the self-cleaning state, so as to perform self-cleaning more effectively.

[0035] In addition, the absence of filter holes on the air guide assembly 12 helps to simplify its structure and facilitates manufacturing. It also helps to reduce the accumulation of dust, particles and other debris in the filter holes, thus reducing the impact of filter hole clogging on the performance of the cleaning device 100. Furthermore, it facilitates the cleaning of the air guide assembly 12, reduces maintenance work, and saves users time and effort.

[0036] See Figures 2 to 6In some embodiments, the outer casing 11 includes a housing 112 and a mounting member 111. The mounting member 111 is connected to the housing 112. The air guide assembly 12 and the filter 13 are mounted on the housing 112 and respectively connected to the mounting member 111. The mounting member 111 is provided with a first air vent 1114 and a second air vent 1115. The second air vent 1115 surrounds the outer periphery of the first air vent 1114. The first air vent 1114 is connected to the first channel 131. When the cleaning device 100 is in the dust suction state, the air guide assembly 12 abuts against the mounting member 111 and closes the second channel 132. When the cleaning device 100 is in the self-cleaning state, the air guide assembly 12 detaches from the mounting member 111 and opens the second channel 132. The second air vent 1115 is connected to the second channel 132.

[0037] Thus, the air guide assembly 12 can open or close the second air vent 1115 according to the corresponding state of the cleaning device 100, so as to open or close the second channel 132, so that the airflow in the cleaning device 100 can flow in a predetermined direction according to the corresponding state of the cleaning device 100, which helps to optimize the airflow path, reduce turbulence and resistance, and improve the airflow efficiency.

[0038] For example, such as Figure 2 and Figure 3 As shown, when the cleaning device 100 is working, the air guide assembly 12 moves upward along the height direction Y of the cleaning device 100 and abuts against the mounting part 111. The second air vent 1115 is closed and the second channel 132 is closed. At this time, the negative pressure airflow in the cleaning device 100 can only flow upward through the first channel 131. The first channel 131 exhausts air through the first air vent 1114, thereby realizing the dust collection work.

[0039] When the cleaning device 100 needs to self-clean, such as Figure 4 and Figure 5 As shown, the air guide assembly 12 moves downward along the height direction Y of the cleaning device 100 and detaches from the mounting part 111. The second air vent 1115 opens and the second channel 132 opens. At this time, the positive pressure airflow in the cleaning device 100 can flow downward through the first channel 131 and the second channel 132. The first channel 131 can take in air through the first air vent 1114, and the second channel 132 can take in air through the second air vent 1115, which helps to increase the air intake of the cleaning device 100 in the self-cleaning state.

[0040] The first air vent 1114 and the second air vent 1115 can be circular, rectangular, elliptical or other shapes, and can be set according to the actual situation.

[0041] The number of second air vents 1115 can be one or more. For example, there can be one second air vent 1115, which is arranged in a ring around the outer periphery of the first air vent 1114. This helps to increase the air intake area of ​​the second air vent 1115 and increase the air intake volume of the cleaning device 100 in the self-cleaning state. Alternatively, there can be two, three, four, five, eight, ten or other numbers of second air vents 1115, which are arranged around the outer periphery of the first air vent 1114. This helps to increase the air intake area of ​​the second air vent 1115 and increase the air intake volume of the cleaning device 100 in the self-cleaning state.

[0042] In other embodiments, the number of second air vents 1115 can also be other, and can be set according to the actual situation.

[0043] In some embodiments, the air guide assembly 12 includes an air guide 121 and an elastic element 122. One end of the elastic element 122 is connected to the mounting member 111, and the other end of the elastic element 122 is connected to the air guide 121. When the cleaning device 100 is in the dust suction state, the elastic element 122 is in the extended state, and the elastic force of the elastic element 122 is suitable for pressing the air guide 121 against the mounting member 111. When the cleaning device 100 is in the self-cleaning state, the elastic element 122 is in the compressed state, and the air guide 121 is disengaged from the mounting member 111. The elastic element 122 can be a spring. The air guide 121 can be arranged in a hollow column shape, which can be specifically configured according to actual conditions.

[0044] Thus, when the cleaning device 100 is in the dust suction state, the air guide 121 can be pressed against the mounting part 111 under the action of the elastic force of the elastic member 122, so as to ensure good sealing of the second channel 132, which helps to reduce the escape of airflow from the connection position of the air guide 121 and the mounting part 111, helps the airflow to flow better in the predetermined direction, helps to better optimize the flow path of the airflow, helps to reduce turbulence and resistance, and helps to improve the flow efficiency of the airflow. When the cleaning device 100 is in the self-cleaning state, the second air outlet 1115 takes in air, and the air force overcomes the elastic force of the elastic member 122, causing the elastic member 122 to be compressed, so that the air guide 121 can be separated from the mounting part 111 and open the second channel 132, thereby ensuring that the airflow smoothly enters the second channel 132 for cleaning.

[0045] In addition, the elastic element 122 can extend and retract in the direction of elastic deformation, which helps guide the movement path of the air guide 121, allowing the air guide 121 to move along the predetermined path and helping to reduce the situation where the air guide 121 deviates from the predetermined path.

[0046] When the cleaning device 100 of this application is in self-cleaning mode, the cleaning device 100 operates by blowing air. At this time, the cleaning device 100 can intake air through the second air inlet 1115, using the airflow to push the air guide 121 to overcome the elastic force of the elastic member 122, thereby opening the second channel 132. This reduces the involvement of electrical components during the self-cleaning process of the cleaning device 100, saving energy. When the cleaning device 100 is in vacuuming mode, the cleaning device 100 operates by suction. Through the adaptive setting of the elastic member 122, the air guide 121 can be reset and pressed against the mounting member 111, thereby closing the second channel 132. This also reduces the involvement of electrical components during the self-cleaning process of the cleaning device 100, saving energy.

[0047] In this way, by setting the moving direction of the air guide 121 and the elastic element 122 to match the airflow direction of the cleaning device 100 in the dust suction state and the self-cleaning state, the involvement of electrical components during the switching process is reduced, which helps to save manufacturing costs and also helps to reduce the situation where other devices occupy the internal space of the cleaning device 100, resulting in the cleaning device 100 being too large, thus helping to improve the reliability of the cleaning device 100.

[0048] See Figure 3 and Figure 5 In some embodiments, the mounting member 111 is provided with a mounting cavity 1111 and a guide portion 1116. The guide portion 1116 is located in the mounting cavity 1111. The elastic member 122 surrounds the outer periphery of the guide portion 1116. The air guide member 121 is located outside the mounting cavity 1111 and is spaced apart from the side wall of the mounting member 111.

[0049] Thus, the mounting component 111 provides space for the installation of the elastic component 122. The mounting component 111 does not obstruct the movement of the air guide component 121, helping to ensure the smooth movement of the air guide component 121 and facilitating position adjustment according to actual needs. The guide portion 1116 can guide the elastic component 122, allowing it to move and deform along a predetermined path. This, in turn, helps guide the movement path of the air guide component 121, ensuring it moves along the predetermined path and reducing the likelihood of the air guide component 121 and the elastic component 122 deviating from their predetermined paths.

[0050] In some embodiments, the mounting member 111 is provided with a first limiting part 1112 and a second limiting part 1113, which are distributed along the height direction Y. When the cleaning device 100 is in the dust suction state, the air guide 121 is pressed against the first limiting part 1112; when the cleaning device 100 is in the self-cleaning state, the air guide 121 is pressed against the second limiting part 1113.

[0051] Thus, the first limiting part 1112 and the second limiting part 1113 can restrict the movement of the air guide 121 in both directions, so that the air guide 121 moves within the predetermined path. This helps to reduce the situation where the air guide 121 deviates from the predetermined path, and also helps to more accurately limit the position of the air guide 121. This helps to reduce the situation where excessive displacement of the air guide 121 affects the performance of the cleaning device 100.

[0052] For example, when the cleaning device 100 is working, the air guide 121 moves upward along the height direction Y of the cleaning device 100, and one side of the air guide 121 abuts against the first limiting part 1112. The first limiting part 1112 restricts the upward movement of the air guide 121, so that the air guide 121 moves within a predetermined path.

[0053] When the cleaning device 100 is in self-cleaning operation, the air guide 121 moves downward along the height direction Y of the cleaning device 100. One side of the air guide 121 disengages from the first limiting part 1112, and the other side of the air guide 121 abuts against the second limiting part 1113. The second limiting part 1113 restricts the upward movement of the air guide 121, so that the air guide 121 moves within a predetermined path.

[0054] Thus, the first limiting part 1112 and the second limiting part 1113 can work together to restrict the movement of the air guide 121 under different cleaning states, so that the air guide 121 can move within a predetermined path when the cleaning device 100 is in the dust suction state and the self-cleaning state, thereby ensuring the normal operation of the air guide 121.

[0055] In some embodiments, the first limiting portion 1112 includes a first limiting sub-portion 1117 and a second limiting sub-portion 1118, the first limiting sub-portion 1117 and the second limiting sub-portion 1118 are respectively located on both sides of the guide portion 1116 in the radial direction, and the first limiting sub-portion 1117 is disposed close to the filter element 13 relative to the second limiting sub-portion 1118.

[0056] This helps increase the stability of the entire structure. When the cleaning device 100 is vacuuming, the first limiting sub-part 1117 and the second limiting sub-part 1118 can provide more stable support for the air guide 121, reducing the shaking of the air guide 121. In addition, the first limiting sub-part 1117 and the second limiting sub-part 1118 also provide redundancy. If one of them malfunctions, the other can still limit the air guide 121, which helps improve the reliability of the cleaning device 100.

[0057] The first limiting sub-part 1117 and the second limiting sub-part 1118 can each be in a ring shape to adapt to the hollow columnar structure of the air guide 121, so as to better restrict the movement of the air guide 121.

[0058] See Figures 7 to 10In some embodiments, the air guide 121 is provided with a flow guide 1215, which is located at the end of the air guide 121 away from the mounting member 111.

[0059] Thus, the airflow guide 1215 can guide the airflow in a predetermined direction, helping to guide the airflow more evenly through the air guide 121 and reducing airflow turbulence and unevenness. When the cleaning device 100 is in self-cleaning operation, the air guide 121 moves downward along the height direction Y of the cleaning device 100 and detaches from the outer casing 11, the second channel 132 opens, and the airflow in the second channel 132 can flow to the position to be cleaned under the action of the airflow guide 1215, thereby improving the cleaning efficiency of the space to be cleaned.

[0060] For example, such as Figure 7 and Figure 8 As shown, the flow guide 1215 has a hollow structure.

[0061] In this way, the airflow in the air guide 121 can enter the space between the outer shell 11 and the air guide 121 through the hollow structure, ensuring that more airflow can clean the outer shell 11 and the space between the outer shell 11 and the air guide 121, which helps to improve the cleaning efficiency of the outer shell 11 and the space between the outer shell 11 and the air guide 121. The hollow structure also helps to reduce the resistance of airflow and helps to reduce the energy consumption of the cleaning device 100.

[0062] For example, such as Figure 9 and Figure 10 As shown, the air guide 121 includes an air guide body 1211 and an air guide sub-body 1212. The air guide body 1211 surrounds the outer periphery of the filter element 13, and the air guide sub-body 1212 is connected to the air guide body 1211 and surrounds the outer periphery of the air guide body 1211. The end of the air guide sub-body 1212 is provided with a flow guide portion 1215, which is located on the side of the air guide sub-body 1212 away from the mounting member 111. The flow guide portion 1215 is inclined towards the outer casing 11 along the height direction Y.

[0063] In this way, the airflow guide 1215 can guide the airflow to the space between the housing 11 and the air guide 121, so that more airflow can clean the housing 11 and the space between the housing 11 and the air guide 121, which helps to improve the cleaning efficiency of the housing 11 and the space between the housing 11 and the air guide 121.

[0064] The air guide body 1211 has an air guide port 1213. A third channel 1214 is formed between the air guide sub-body 1212 and the air guide body 1211. The air guide port 1213 is connected to the third channel 1214. The second channel 132 and the third channel 1214 are not connected to each other. When the cleaning device 100 is in the dust suction state, the air guide component 121 abuts against the mounting component 111. The mounting component 111 seals the air guide port 1213 to close the second channel 132 and the third channel 1214. When the cleaning device 100 is in the self-cleaning state, the air guide component 121 detaches from the mounting component 111. The mounting component 111 opens the air guide port 1213 to open the second channel 132 and the third channel 1214.

[0065] Thus, the cleaning device 100 can adjust the position of the air guide 121 according to actual needs to perform dust suction or self-cleaning. The air guide 121 can open or close the second channel 132 and the third channel 1214 according to the corresponding state of the cleaning device 100, so that the airflow in the cleaning device 100 can flow in a predetermined direction according to the corresponding state of the cleaning device 100. The guide part 1215 can guide the airflow in the third channel 1214 to the space between the outer shell 11 and the air guide 121, which helps to optimize the airflow path, reduce turbulence and resistance, and improve the airflow efficiency.

[0066] The system includes multiple air vents 1213 and multiple third channels 1214, with each air vent 1213 corresponding to a specific number of third channels 1214. For example, the number of air vents 1213 can be two, three, four, or other numbers, and the number of third channels 1214 can also be two, three, four, or other numbers, depending on the actual situation.

[0067] Thus, multiple air inlets 1213 and multiple third channels 1214 help increase the air intake of the air guide 121, help ensure sufficient air intake within the air guide 121, and help ensure thorough cleaning of the air guide 121.

[0068] Revisit Figures 6 to 8 In some embodiments, the air guide 121 is further provided with a flow-guiding reinforcement 1216, which is located on the side of the air guide 121 away from the filter element 13, and the flow guide 1215 avoids the flow-guiding reinforcement 1216. The flow-guiding reinforcement 1216 may be a reinforcing rib.

[0069] Due to the abrupt change in shape at the guide section 1215, stress will concentrate at this point. By providing the flow-guiding reinforcement 1216, the overall strength and rigidity of the air guide 121 are enhanced, reducing deformation of the surrounding structure when airflow passes through it at high speed. This helps maintain the shape stability of the air guide 121 and reduces the likelihood of breakage. Furthermore, the flow-guiding reinforcement 1216 helps reduce the wall thickness of the air guide 121, thus reducing weight and saving material costs.

[0070] In some embodiments, the outer casing 11 is further provided with a reinforcing part 113, which is connected to the mounting member 111 and surrounds the outer periphery of the first air vent 1114. The reinforcing part 113 is located between the first air vent 1114 and the second air vent 1115.

[0071] When the cleaning device 100 is operating, it generates strong airflow and negative pressure. The area between the first air vent 1114 and the second air vent 1115 is at risk of deformation and failure due to the impact of the airflow. By providing a reinforcing section 113 between the first air vent 1114 and the second air vent 1115, the structural strength of this area is increased, reducing the likelihood of deformation and failure, and extending the service life of the air guide 121. Furthermore, the reinforcing section 113 also helps guide the airflow through the first air vent 1114 and the second air vent 1115 effectively, reducing airflow turbulence and thus lowering the noise level of the cleaning device 100 during operation.

[0072] Revisit Figure 1 , Figure 2 and Figure 4 In some embodiments, the cleaning device 100 includes a base station 20 and a vacuum cleaner 10. The vacuum cleaner 10 includes the aforementioned housing 11, air guide assembly 12, and filter element 13. The vacuum cleaner 10 is detachably inserted into the base station 20. When the cleaning device 100 is in vacuuming mode, the vacuum cleaner 10 is detached from the base station 20; when the cleaning device 100 is in self-cleaning mode, the vacuum cleaner 10 is inserted into the base station 20.

[0073] Thus, when the vacuum cleaner 10 is working, it can be detached from the base station 20 to ensure that the vacuum cleaner 10 can continue to work; when the cleaning device 100 needs to self-clean, it can be inserted into the base station 20 to ensure that the cleaning device 100 can self-clean.

[0074] In summary, the cleaning device 100 provided in this embodiment of the invention has an air guide assembly 12 and a filter element 13 both installed in a housing 11. The air guide assembly 12 is movably arranged around the outer periphery of the filter element 13 along the height direction Y of the cleaning device 100. The filter element 13 has a first channel 131, and a second channel 132 is formed between the air guide assembly 12 and the filter element 13. The first channel 131 and the second channel 132 are not interconnected. The cleaning device 100 has a dust suction state and a self-cleaning state. When the cleaning device 100 is in the dust suction state, the air guide assembly 12 abuts against the housing 11 and closes the second channel 132, and the airflow in the cleaning device 100 flows through the first channel 131. When the cleaning device 100 is in the self-cleaning state, the air guide assembly 12 detaches from the housing 11 and opens the second channel 132, and the airflow in the cleaning device 100 flows through the first channel 131 and the second channel 132. Thus, the cleaning device 100 can adjust the position of the air guide component 12 according to actual needs to perform dust suction or self-cleaning. The air guide component 12 can open or close the second channel 132 according to the corresponding state of the cleaning device 100, so that the airflow in the cleaning device 100 can flow in a predetermined direction according to the corresponding state of the cleaning device 100, which helps to optimize the airflow path, reduce turbulence and resistance, and improve the airflow efficiency.
