Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to an air flow processing system and a dust collecting device. BACKGROUND

[0002] At present, some models of dust collectors on the market are integrated dust and mop type dust collectors, that is, a module for realizing the mopping function and a corresponding clean water tank are added to the dust collector, so that the dust collector can perform wet cleaning and dust collection on the surface to be cleaned.

[0003] When the dust collector performs wet cleaning on the ground, water is likely to remain on the ground, resulting in water in the air flow sucked by the dust collector. However, the air flow processing system currently used by the dust collector mainly realizes the separation of dust and impurities and air, and the separation effect of liquid and gas is limited. The air flow processed by the air flow processing system still carries water, resulting in poor performance of the dust collector. SUMMARY

[0004] In view of the above problems, the present application provides an air flow processing system which can improve the separation effect of gas and liquid, ensure that clean and dry air is discharged from the air outlet, and reduce the risk of damage to the air flow driving element.

[0005] The present application provides an air flow processing system for a dust collecting device, comprising: a dust cup, an inner side of the dust cup being provided with a partition plate, the partition plate extending along an axial direction of the dust cup and separating an inner cavity of the dust cup into a first dust collecting cavity and a second dust collecting cavity arranged side by side, a cavity wall of the first dust collecting cavity being provided with an air inlet, and a cavity wall of the second dust collecting cavity being provided with an air outlet; an air flow separator, at least part of a structure of the air flow separator being arranged in the first dust collecting cavity, the second dust collecting cavity being configured to realize liquid-gas separation; and an air flow driving element, the air flow driving element being located on a downstream side of the air flow separator in a flow direction of the air flow, and the air flow driving element driving the air flow to flow from the first dust collecting cavity to the second dust collecting cavity via the air flow separator.

[0006] According to the air flow processing system of the present application, the inner cavity of the dust cup is separated into the first dust collecting cavity and the second dust collecting cavity by the partition plate, the air flow path is lengthened and the number of changes in the direction of the air flow is increased. At least part of the structure of the air flow separator is arranged in the first dust collecting cavity, so that the separation of dust and impurities and air, and the separation of part of the water and air can be realized in the first dust collecting cavity. The second dust collecting cavity can further separate the water and air, improve the separation effect of the air flow processing system on the gas and liquid, ensure that clean and dry air is discharged from the air outlet, and prevent sewage droplets from being discharged into the indoor environment. Moreover, since the air flow driving element is arranged on the downstream side of the air flow separator, most of the water in the air flow can be separated in the first dust collecting cavity, so as to reduce the risk of water droplets entering the interior of the air flow driving element, thereby reducing the risk of damage to the air flow driving element.

[0007] In some embodiments, the exhaust port is arranged on a side wall of the second dust collecting cavity, and the dust cup further comprises a flow channel baffle, which is arranged in the second dust collecting cavity and on a side of the exhaust port away from the airflow driving element in the axial direction of the dust cup. The flow channel baffle is configured to guide the airflow in the second dust collecting cavity to the exhaust port.

[0008] In this way, the flow channel baffle is arranged to block the airflow from flowing in the axial direction of the dust cup, so that the airflow changes direction under the action of the flow channel baffle and is discharged from the exhaust port. This can further increase the complexity of the airflow flow path and facilitate better gas-liquid separation.

[0009] In some embodiments, the flow channel baffle separates the second dust collecting cavity into a liquid-gas separation flow channel and a third accommodation chamber arranged in sequence in the axial direction of the dust cup. The exhaust port is arranged on a side wall of the liquid-gas separation flow channel. The flow channel baffle is provided with a separation hole. The liquid-gas separation flow channel and the third accommodation chamber are communicated through the separation hole.

[0010] In this way, after the airflow enters the second dust collecting cavity, it first flows along the liquid-gas separation flow channel. When it flows to the flow channel baffle, the airflow changes direction and is discharged from the exhaust port due to the blocking of the flow channel baffle. In this process, the weight of the liquid droplets is greater than that of the air, so that the liquid droplets enter the third accommodation chamber through the separation hole under the action of inertia, thereby realizing gas-liquid separation to prevent sewage droplets from being discharged from the dust collector along with the airflow and entering the indoor environment, and improving the user experience.

[0011] In some embodiments, the airflow treatment system further comprises a flow guide member arranged in the liquid-gas separation flow channel. One end of the flow guide member is spaced apart from the flow channel baffle in the axial direction of the dust cup. The flow guide member separates the liquid-gas separation flow channel into a first air outlet section and a second air outlet section arranged in sequence in the direction of the airflow. The first air outlet section is located on the inner side of the flow guide member, the second air outlet section is located on the outer side of the flow guide member, and the exhaust port is located in the second air outlet section. The flow channel baffle is configured to guide the airflow in the first air outlet section to the second air outlet section.

[0012] In this way, by arranging the flow guide member, the length of the liquid-gas separation flow channel can be extended to improve the liquid-gas separation effect. On the other hand, by arranging the flow guide member, the liquid-gas separation flow channel is divided into two parts in opposite directions of the airflow. The space between the end of the flow guide member and the flow channel baffle is used to adjust the direction of the airflow. Thus, during the air direction adjustment process, the liquid-gas separation is realized by using the principle of inertia, in which the liquid enters the third accommodation chamber and the gas enters the second air outlet section and is discharged from the exhaust port.

[0013] In some embodiments, the airflow driving member is further located on an upstream side of the second dust collection cavity in the airflow direction.

[0014] In this way, the distance between the airflow driving member and the first and second dust collection cavities can be shortened, so that the airflow driving member can provide the maximum driving force for the airflow in the first and second dust collection cavities to the maximum extent, and the inertia of the airflow at the flow channel baffle can be increased to better achieve liquid-gas separation and ensure the separation effect.

[0015] In some embodiments, the airflow driving member is located on the same side of the first and second dust collection cavities in the axial direction of the dust cup.

[0016] In this way, the space of the airflow treatment system in the height direction can be saved, and the overall layout is simple and easy to implement.

[0017] In some embodiments, the outer wall of the airflow separator and the inner wall of the first dust collection cavity jointly define an air inlet flow channel, the inner side of the airflow separator defines a dust-gas separation flow channel, the air inlet flow channel and the dust-gas separation flow channel extend in the axial direction of the dust cup, the air inlet is arranged on the side wall of the air inlet flow channel, the airflow separator is provided with a communication port, the communication port communicates the air inlet flow channel and the dust-gas separation flow channel, and the outlet of the dust-gas separation flow channel communicates with the inlet of the airflow driving member.

[0018] In this way, after the airflow enters the dust cup from the air inlet, it first enters the air inlet flow channel, then enters the dust-gas separation flow channel through the communication port, is separated and treated by the airflow separator, then enters the second dust collection cavity through the airflow driving member, and finally is discharged from the air outlet. By adjusting the structure and arrangement of the air inlet flow channel and the dust-gas separation flow channel, the separation effect of dust impurities, liquid droplets and air in the airflow in the first dust collection cavity can be improved, the water content in the airflow entering the second dust collection cavity can be reduced, the second dust collection cavity is prepared for further separating water and air, and the water-air separation pressure in the second dust collection cavity is reduced, so as to comprehensively improve the airflow treatment effect of the airflow treatment system and improve the user experience.

[0019] In some embodiments, the outer wall of the airflow separator and the inner wall of the first dust collection cavity are spaced apart in the circumferential direction, so that the air inlet flow channel surrounds the dust-gas separation flow channel.

[0020] In this way, the airflow in the air inlet flow channel can enter the dust-gas separation flow channel from the communication port in the circumferential direction.

[0021] In some embodiments, the communication port and the air inlet are arranged in the axial direction of the dust cup.

[0022] Therefore, the flow path of the air flow in the first dust collection cavity is prolonged, and the dust-air separation effect and the liquid-air separation effect are improved.

[0023] In some embodiments, the air inlet is located at one end of the flow passage wall of the air inlet flow passage close to the air flow driving member, and the communication port is located at a middle region of the dust-air separation flow passage along the dust cup axis.

[0024] Therefore, the distance between the air inlet and the communication port is further prolonged, the flow path length of the air flow in the air inlet flow passage is prolonged, the dust-air separation effect and the liquid-air separation effect are improved, and the air inlet flow passage and the dust-air separation flow passage located below the communication port can be used as a space for accommodating dust impurities and moisture.

[0025] In some embodiments, a portion of the air inlet flow passage located on a side of the communication port away from the air flow driving member constitutes a first accommodation chamber, and a portion of the dust-air separation flow passage located on a side of the communication port away from the air flow driving member constitutes a second accommodation chamber.

[0026] Therefore, the first accommodation chamber can accommodate dust, hair and other impurities and moisture separated in the air inlet flow passage, and the second accommodation chamber can accommodate dust, hair and other impurities and moisture separated in the dust-air separation flow passage.

[0027] In some embodiments, the dust cup comprises an end cover arranged at one end of the first dust collection cavity and the second dust collection cavity opposite to the air flow driving member, and the end cover is used to simultaneously open or close the first dust collection cavity and the second dust collection cavity.

[0028] Therefore, the user can simultaneously empty the first dust collection cavity and the second dust collection cavity of the dust cup in one opening operation, and the operation is simple and convenient, which improves the user experience.

[0029] In some embodiments, the air flow driving member is configured to operate in any one of a dry air flow condition and a wet air flow condition.

[0030] Therefore, the air flow driving member is more adaptable and practical, the reliability of the dust collection device is improved, and the user experience is further improved.

[0031] In some embodiments, the air flow driving member defines a transition flow passage, two ends of the transition flow passage are respectively communicated with the first dust collection cavity and the second dust collection cavity, the air flow driving member comprises an electrical element, and the electrical element is insulated from the transition flow passage.

[0032] Therefore, the airflow driving member can be smoothly driven to drive the airflow from the first dust collecting cavity side to the second dust collecting cavity side via the airflow driving member, and meanwhile, the moisture in the airflow can be prevented from contacting the electrical element to damage the electrical element and affect the normal operation of the dust collection equipment.

[0033] In some embodiments, the airflow driving member is a dry-wet dual-purpose motor.

[0034] Therefore, the moisture can be prevented from entering the airflow driving member to damage the airflow driving member, so that the adaptability of the airflow driving member is stronger, the airflow driving member is more practical, the reliability of the dust collection equipment is improved, and the user experience can be further improved.

[0035] The application further provides a dust collection equipment, which comprises a main machine provided with a main air duct, a cleaning assembly for cleaning a to-be-cleaned surface, the cleaning assembly being provided with a dust suction port in communication with the main air duct, and the airflow treatment system according to the first aspect of the application, which is arranged on the main machine and has an air inlet in communication with the main air duct.

[0036] According to the dust collection equipment of the application, the airflow treatment system is arranged, so that the separation effect of air and liquid in the airflow can be improved, clean and dry air can be discharged from the air outlet, sewage droplets can be prevented from being discharged into the indoor environment, the risk of damage to the airflow driving member can be reduced, and the user experience can be improved.

[0056] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0057] At present, some models of vacuum cleaners on the market are integrated with a mop, that is, a module for realizing the mopping function and a corresponding water tank are added to the roller brush of the vacuum cleaner, so that the vacuum cleaner can perform wet cleaning and dust suction on the surface to be cleaned. When the vacuum cleaner performs wet cleaning on the ground, water is likely to remain on the ground, resulting in that the air flow sucked by the vacuum cleaner contains water. However, the air flow treatment system currently used by the vacuum cleaner mainly realizes the separation of dust and impurities from air, and the separation effect of liquid and gas is limited. The air flow treated by the air flow treatment system still carries water, resulting in poor performance of the vacuum cleaner.

[0058] Therefore, the present application provides an air flow treatment system and a vacuum cleaning device. The first dust collection cavity can separate dust and impurities from air and separate part of water from air, and the second dust collection cavity can further separate water from air, thereby improving the separation effect of the air flow treatment system on gas and liquid, ensuring that clean and dry air is discharged from the air outlet, and preventing sewage droplets from being discharged into the indoor environment. Moreover, the risk of water droplets entering the internal part of the air flow driving member can be reduced, thereby reducing the risk of damage to the air flow driving member.

[0059] The air flow treatment system 100 of the present embodiment is used in a vacuum cleaning device, which can be a handheld vacuum cleaner. The vacuum cleaning device can be an integrated vacuum cleaner with a mop, that is, the vacuum cleaner is equipped with a mopping module and a dust suction module. The mopping module can spray water on the ground or other surface to be cleaned and mop the ground, and the dust suction module can be used to suck impurities on the ground. It can be understood that, since the air flow treatment system 100 can perform wet cleaning, the air flow sucked by the dust suction module can contain sewage droplets in addition to hair, impurities and other objects.

[0060] In combination Figures 1-5 The air flow treatment system 100 of the present embodiment can be part of the dust suction module of the vacuum cleaning device. The air flow treatment system 100 can include a dust cup 1, an air flow separator 2 and an air flow driving member 3.

[0061] The cross section of the dust cup 1 can be circular, oblong or other shapes. The inner side of the dust cup 1 is provided with a partition plate 11 extending along the axial direction of the dust cup 1 and separating the inner cavity of the dust cup 1 into the first dust collection cavity 12 and the second dust collection cavity 13 arranged side by side, that is, the side-by-side arrangement direction of the first dust collection cavity 12 and the second dust collection cavity 13 is perpendicular to the axial direction of the dust cup 1. The cavity wall of the first dust collection cavity 12 is provided with an air inlet 15, and the cavity wall of the second dust collection cavity 13 is provided with an air outlet 16. That is, when the air flow sucked by the vacuum cleaning device flows through the dust cup 1, it enters the first dust collection cavity 12 from the air inlet 15, then flows through the second dust collection cavity 13, and finally is discharged from the air outlet 16.

[0062] At least part of the structure of the airflow separator 2 can be arranged in the first dust collecting cavity 12. For example, part of the structure of the airflow separator 2 can be arranged on one side of the first dust collecting cavity 12, and the other part of the structure can be arranged on one side of the second dust collecting cavity 13. Alternatively, all of the structure of the airflow separator 2 can be arranged on one side of the first dust collecting cavity 12.

[0063] The airflow separator 2 can be a cyclone separator or other separation device. The airflow separator 2 is configured to separate dust and air in the first dust collecting cavity 12, so as to separate solid dust, hair and other impurities from the air. The separated solid dust, hair and other impurities, as well as part of the water, are retained in the first dust collecting cavity 12, while the air and part of the water vapor enter the second dust collecting cavity 13.

[0064] The second dust collecting cavity 13 is configured to separate liquid and air. That is, when the airflow containing water vapor flows through the second dust collecting cavity 13, the water in the airflow is separated from the air, so as to ensure that clean and dry air is discharged from the air outlet 16. The trapped water vapor can be temporarily stored in the second dust collecting cavity 13 and finally cleaned. For example, a water-absorbing material can be arranged in the second dust collecting cavity 13. Alternatively, the flow channel structure in the second dust collecting cavity 13 can be configured to change the direction of the airflow, so as to separate the water and the air by using the principle of inertia. Of course, other ways of separating the water and the air can also be used.

[0065] The airflow driving member 3 is arranged on the downstream side of the airflow separator 2 in the airflow direction. In this way, the airflow driving member 3 drives the airflow to flow from the first dust collecting cavity 12 to the second dust collecting cavity 13 through the airflow separator 2, and finally discharged from the air outlet 16.

[0066] According to the airflow treatment system 100 of the embodiment of the present application, the inner cavity of the dust cup 1 is divided into the first dust collecting cavity 12 and the second dust collecting cavity 13 by the partition plate 11, the airflow path is lengthened and the number of times of changing the direction of the airflow is increased. At least part of the structure of the airflow separator 2 is arranged in the first dust collecting cavity 12, so that the separation of dust and air, as well as the separation of part of the water and the air, can be achieved in the first dust collecting cavity 12. The second dust collecting cavity 13 can further separate the water and the air, so as to improve the separation effect of the airflow treatment system 100 on the liquid and the air, ensure that clean and dry air is discharged from the air outlet 16, and prevent sewage droplets from being discharged into the indoor environment. In addition, since the airflow driving member 3 is arranged on the downstream side of the airflow separator 2, and most of the water in the airflow can be separated in the first dust collecting cavity 12, the risk of water droplets entering the interior of the airflow driving member 3 can be reduced, so as to reduce the risk of damage to the airflow driving member 3.

[0067] In some embodiments, the airflow treatment system 100 can further comprise a filter arranged in the second dust collecting cavity 13. Figures 2-5The exhaust port 16 can be arranged on the side wall of the second dust collecting cavity 13, that is, the air flow treatment system 100 can realize lateral air outlet. The dust cup 1 can further include a flow channel baffle 14, which is arranged in the second dust collecting cavity 13 and on the side of the exhaust port 16 away from the air flow driving member 3 in the axial direction of the dust cup 1.

[0068] The flow channel baffle 14 is configured to guide the air flow in the second dust collecting cavity 13 to the exhaust port 16. The flow channel baffle 14 can be a flat plate, an arc-shaped plate or other configurations. Since the partition plate 11 extends in the axial direction of the dust cup 1 and the air flow driving member 3 is arranged at one axial end of the second dust collecting cavity 13, when the air flow enters the second dust collecting cavity 13 through the air flow driving member 3, the air flow mainly flows in the axial direction of the dust cup 1. Since the exhaust port 16 is arranged on the side wall of the second dust collecting cavity 13, the flow channel baffle 14 is arranged in the embodiment to block the air flow from flowing in the axial direction of the dust cup 1, so that the air flow changes direction under the action of the flow channel baffle 14 and is discharged from the exhaust port 16. This can further increase the complexity of the air flow path and is beneficial to better air-liquid separation.

[0069] In some embodiments, in combination with Figure 4 and Figure 5 The flow channel baffle 14 divides the second dust collecting cavity 13 into a distributed liquid-air separation flow channel 131 and a third accommodating chamber 134, which are sequentially distributed in the axial direction of the dust cup 1, and the liquid-air separation flow channel 131 is closer to the first dust collecting cavity 12 in the air flow path. The exhaust port 16 is arranged on the side wall of the liquid-air separation flow channel 131, and the flow channel baffle 14 is provided with a separation hole 141, and the liquid-air separation flow channel 131 and the third accommodating chamber 134 are communicated through the separation hole 141.

[0070] In this way, after the air flow enters the second dust collecting cavity 13 through the air flow driving member 3, it first flows along the liquid-air separation flow channel 131 and changes direction to be discharged from the exhaust port 16 when it flows to the flow channel baffle 14. In this process, the weight of the liquid droplets is greater than that of the air, so that the liquid droplets enter the third accommodating chamber 134 through the separation hole 141 under the action of inertia. In this way, air-liquid separation can be realized to prevent sewage droplets from being discharged from the dust collector with the air flow and entering the indoor environment, which is beneficial to improve the user experience.

[0071] In some embodiments, in combination with Figure 3 and Figure 4, the air flow treatment system 100 can further comprise a flow guide 5. Specifically, the flow guide 5 is arranged in the liquid-gas separation flow channel 131, one end of the flow guide 5 is arranged along the axial direction of the dust cup 1 and spaced apart from the flow channel baffle 14, the flow guide 5 divides the liquid-gas separation flow channel 131 into a first air outlet section 132 and a second air outlet section 133 arranged in sequence along the air flow direction, the first air outlet section 132 is located at the inner side of the flow guide 5, the second air outlet section 133 is located at the outer side of the flow guide 5, the exhaust port 16 is located in the second air outlet section 133, and the flow channel baffle 14 is configured to guide the air flow in the first air outlet section 132 to the second air outlet section 133.

[0072] In this way, by arranging the flow guide 5, on the one hand, the length of the liquid-gas separation flow channel 131 can be extended to improve the liquid-gas separation effect, and on the other hand, by arranging the flow guide 5, the liquid-gas separation flow channel 131 is divided into two parts in opposite air flow directions, and the space between the end of the flow guide 5 and the flow channel baffle 14 is used to adjust the air flow direction, so that during the air flow direction adjustment, liquid-gas separation is realized, in which liquid enters the third accommodation chamber 134 and gas enters the second air outlet section 133 and is discharged from the exhaust port 16.

[0073] In some optional embodiments, the flow guide 5 can comprise a flow guide side plate, a first end (e.g., the upper end of the flow guide side plate) of the flow guide side plate extends to the inlet of the liquid-gas separation flow channel 131 and is attached to the side wall on the side of the exhaust port 16 of the liquid-gas separation flow channel 131, and a second end (e.g., the lower end of the flow guide side plate) of the flow guide side plate extends obliquely towards the side wall on the side opposite to the exhaust port 16 of the liquid-gas separation flow channel 131, and the second end extends to the lower side of the exhaust port 16 and is spaced apart from the flow channel baffle 14 along the axial direction. In this way, the flow guide side plate can change the flow direction of the air flow before it reaches the exhaust port 16, thereby realizing the separation of liquid and air by inertia.

[0074] Further, referring to Figure 4 , the flow guide side plate can comprise a first section 51 and a second section 52. Specifically, the first section 51 and the second section 52 are arranged in sequence along the axial direction of the dust cup 1 and connected, the first section 51 is located above the exhaust port 16, the first end of the flow guide side plate, i.e., the first section 51, is directed towards the air flow driving member 3, and the first section 51 is attached to the side wall of the liquid-gas separation flow channel 131 on the side where the exhaust port 16 is arranged. The second section 52 is arranged opposite to the exhaust port 16, the second end of the flow guide side plate, i.e., the second section 52, is directed towards the flow channel baffle 14, and the second section 52 is inclined relative to the axial direction of the dust cup 1 to define the first air outlet section 132 and the second air outlet section 133 on the two sides of the second section 52, respectively. In this way, the configuration of the flow guide side plate is relatively simple and easy to implement.

[0075] Optionally, the flow guide side plate can be a single plate structure, for example, the flow guide side plate is formed as an arc-shaped plate; or the flow guide side plate can also be a part of the structure of the peripheral wall of the flow guide 5.

[0076] Further, in combination with Figure 2 and Figure 4 , the flow guide 5 is formed as a ring-shaped flow guide sleeve, the flow guide side plate constitutes a first side wall of the flow guide sleeve facing the exhaust port 16, and the flow guide sleeve also has a second side wall opposite to the flow guide side plate, which can be attached to the side wall of the liquid-gas separation flow channel 131 on the side not provided with the exhaust port 16. In this way, the structure of the flow guide 5 is relatively simple, and the flow guide 5 is easier to assemble into the second dust collecting cavity 13.

[0077] In some embodiments, in combination with Figure 4 and Figure 5 , the height of the partition plate 11 along the axial direction of the dust cup 1 is lower than the height of the end of the dust cup 1, the flow guide 5 and the airflow shunt are connected at one end close to the airflow driving member 3, and the connection part of the airflow shunt and the flow guide 5 is supported at the end of the partition plate 11. In this way, the airflow shunt and the flow guide 5 can be supported and fixed by the partition plate 11, and the connection part of the airflow shunt and the flow guide 5 is supported at the end of the partition plate 11, which can seal the gap between the airflow separator 2 and the partition plate 11 and the gap between the flow guide 5 and the partition plate 11, and ensure that the airflow can only enter the liquid-gas separation flow channel 131 from the dust-gas separation flow channel 122 through the airflow driving member 3.

[0078] In some embodiments, the airflow driving member 3 is also located on the upstream side of the second dust collecting cavity 13 along the airflow direction, that is, the airflow driving member 3 is located on the downstream side of the airflow separator 2 along the airflow direction and on the upstream side of the second dust collecting cavity 13 along the airflow direction. In this way, the distance between the airflow driving member 3 and the first dust collecting cavity 12 and the second dust collecting cavity 13 can be shortened at the same time, so as to ensure that the airflow driving member 3 can provide the maximum driving force for the airflow in the first dust collecting cavity 12 and the second dust collecting cavity 13 to the maximum extent, and also increase the inertia of the airflow at the flow channel baffle 14 to better achieve liquid-gas separation and ensure the separation effect.

[0079] Optionally, the airflow driving member 3 is located on the same side of the first dust collecting cavity 12 and the second dust collecting cavity 13 along the axial direction of the dust cup 1, for example, the airflow driving member 3 can be located on the upper side of the first dust collecting cavity 12 and the second dust collecting cavity 13 when the airflow treatment system 100 is vertically placed. It can be understood that the airflow driving member 3 is located at the intersection of the first dust collecting cavity 12 and the second dust collecting cavity 13. In this way, it is helpful to save the space of the airflow treatment system 100 in the height direction.

[0080] In some embodiments, in combination with Figure 3 and Figure 4The outer wall of the airflow separator 2 and the inner wall of the first dust collecting cavity 12 jointly define an air inlet flow channel 121, and the inner side of the airflow separator 2 defines a dust-air separation flow channel 122. For example, the airflow separator 2 and the inner wall of the first dust collecting cavity 12 are spaced apart in the circumferential direction, and the air inlet flow channel 121 surrounds the dust-air separation flow channel 122; or the airflow separator 2 is in contact with the inner wall of the first dust collecting cavity 12 in part of the circumferential direction, and the air inlet flow channel 121 does not completely surround the dust-air separation flow channel 122 in the circumferential direction, and the air inlet flow channel 121 is arranged side by side with the dust-air separation flow channel 122, and the arrangement direction is perpendicular to the axial direction of the dust cup 1.

[0081] The air inlet flow channel 121 and the dust-air separation flow channel 122 extend in the axial direction of the dust cup 1, the air inlet 15 is arranged on the side wall of the air inlet flow channel 121, the airflow separator 2 is provided with a communication port 21, the communication port 21 communicates the air inlet flow channel 121 and the dust-air separation flow channel 122, and the outlet of the dust-air separation flow channel 122 communicates with the inlet of the airflow driving member 3. For example, when the air inlet flow channel 121 and the dust-air separation flow channel 122 are flush with each other at the end away from the airflow driving member, for example, the bottom end, that is, the airflow separator 2 extends to the bottom wall of the first dust collecting cavity 12, the communication port 21 can be arranged on the side of the separator; the bottom end of the dust-air separation flow channel 122 is away from the bottom end of the air inlet flow channel 121 by a certain distance, that is, the bottom end of the airflow separator is away from the bottom wall of the first dust collecting cavity 12 by a certain distance, so that when the air inlet flow channel 121 surrounds the airflow separator 2 from the circumferential direction and the bottom, the communication port 21 can be arranged on the side of the separator or the bottom of the separator.

[0082] In this way, after the airflow enters the dust cup 1 from the air inlet 15, it first enters the air inlet flow channel 121, then enters the dust-air separation flow channel 122 through the communication port 21, is separated by the airflow separator 2, then enters the second dust collecting cavity 13 through the airflow driving member 3, and finally is discharged from the air outlet 16. By adjusting the structure and arrangement of the air inlet flow channel 121 and the dust-air separation flow channel 122, the separation effect of dust impurities, liquid droplets and air in the airflow in the first dust collecting cavity 12 can be improved, the water content in the airflow entering the second dust collecting cavity 13 can be reduced, the second dust collecting cavity 13 is prepared for further separating water and air, and the water-air separation pressure in the second dust collecting cavity 13 is reduced, so that the airflow treatment effect of the airflow treatment system 100 is improved comprehensively, and the user experience is improved.

[0083] Of course, the present application does not make specific limitations in this regard, and the structure of the air inlet flow channel 121 and the dust-air separation flow channel 122 can be reasonably set according to actual needs.

[0084] In some embodiments, with reference to Figure 3The outer wall of the airflow separator 2 is spaced apart from the inner wall of the first dust collecting cavity 12 in the circumferential direction, so that the air inlet flow channel 121 surrounds the dust-air separation flow channel 122. Correspondingly, the communication port 21 can extend in the circumferential direction of the airflow separator 2, so that the airflow in the air inlet flow channel 121 can enter the dust-air separation flow channel 122 from the communication port 21 in the circumferential direction.

[0085] In some embodiments, referring to Figure 3 and Figure 4 The communication port 21 is arranged to be axially offset from the air inlet 15, so that the flow path of the airflow in the first dust collecting cavity 12 can be extended, which is conducive to improving the dust-air separation effect and the liquid-air separation effect.

[0086] In some embodiments, referring to Figure 3 The air inlet 15 is located at one end of the flow channel wall of the air inlet flow channel 121 close to the airflow driving member 3, and the communication port 21 is located in the middle region of the dust-air separation flow channel 122 in the axial direction of the dust cup 1, so that the distance between the air inlet 15 and the communication port 21 can be further extended, thereby extending the flow path length of the airflow in the air inlet flow channel 121, which is conducive to improving the dust-air separation effect and the liquid-air separation effect.

[0087] It should be emphasized that the middle region here does not only refer to the exact middle position of the dust-air separation flow channel 122 in the axial direction of the dust cup 1, but also includes the adjacent regions on both sides of the exact middle position. For example, the dust-air separation flow channel 122 can be divided into three equal parts in the axial direction of the dust cup 1, and the middle region is the middle part, so that the air inlet flow channel 121 and the dust-air separation flow channel 122 on the lower side of the communication port 21 can serve as a space for accommodating dust and water.

[0088] In some embodiments, referring to Figures 3-5 The part of the air inlet flow channel 121 on the side away from the airflow driving member 3 of the communication port 21 constitutes a first accommodating chamber 1211, and the part of the dust-air separation flow channel 122 on the side away from the airflow driving member 3 of the communication port 21 constitutes a second accommodating chamber 1221. In this way, the first accommodating chamber 1211 can accommodate the dust, hair and other impurities and water separated out of the air inlet flow channel 121, and the second accommodating chamber 1221 can accommodate the dust, hair and other impurities and water separated out of the dust-air separation flow channel 122.

[0089] In some embodiments, in combination with Figures 3-5, the dust cup 1 can include an end cover 4 arranged at an end of the first dust collecting cavity 12 and the second dust collecting cavity 13 along an axial direction of the dust cup 1 and opposite to the airflow driving member 3, for example, a lower end of the dust cup 1, and the end cover 4 is used to simultaneously open or close the first dust collecting cavity 12 and the second dust collecting cavity 13. In other words, the end cover 4 can simultaneously open the first accommodating chamber 1211, the second accommodating chamber 1221 and the third accommodating chamber 134, so that the user can simultaneously empty the plurality of accommodating chambers of the dust cup 1 in one opening operation, which is simple and convenient, and is beneficial to improving the user experience.

[0090] Optionally, referring to Figure 4 and Figure 5 , in order to improve the sealing performance of the first accommodating chamber 1211, the second accommodating chamber 1221 and the third accommodating chamber 134 when the end cover 4 is closed to the main body of the dust cup 1, the airflow treatment system 100 further includes a plurality of sealing members. The plurality of sealing members include a first sealing member 6a, a second sealing member 6b and a third sealing member 6c, the first sealing member 6a can be arranged between the outer peripheral wall end of the dust cup 1 and the end cover 4; the second sealing member 6b is arranged between the end of the airflow separator 2 and the end cover, and the third sealing member 6c is arranged between the end of the partition plate 11 and the end cover.

[0091] Optionally, since the partition plate 11 serves as part of the peripheral wall of the first accommodating chamber 1211 and part of the peripheral wall of the third accommodating chamber 134, the first sealing member 6a and the third sealing member 6c can be an integral part that simultaneously seals the first accommodating chamber 1211 and the third accommodating chamber 134.

[0092] Optionally, the end cover 4 can be provided with a sealing groove corresponding to the sealing member, and the sealing member is embedded in the corresponding sealing groove to improve the installation stability of the plurality of sealing members, thereby improving the sealing performance of each accommodating chamber.

[0093] Further, referring to Figure 5 , the outer peripheral wall of the dust cup 1 is provided with a first matching groove corresponding to the first sealing member, part of the structure of the first sealing member 6a is embedded in the sealing groove on the end cover 4, and the other part is embedded in the first matching groove; correspondingly, the partition plate 11 is provided with a second matching groove corresponding to the third sealing member, part of the structure of the third sealing member 6c is embedded in the sealing groove on the end cover 4, and the other part is embedded in the second matching groove. In this way, the overall sealing performance of the first dust collecting cavity 12 and the second dust collecting cavity 13 can be further improved.

[0094] In some embodiments, the airflow driving member 3 is configured to operate in either of the dry airflow condition and the wet airflow condition, that is, the airflow driving member 3 of the present embodiments can work in both the dry airflow condition and the wet airflow condition, that is, the airflow driving member 3 can be free from dry dust impurities affecting its normal operation and service life, and can also avoid water vapor entering the inside of the airflow driving member 3, affecting the normal operation of the electrical elements and causing damage. In this way, the airflow driving member 3 is more adaptable and more practical, improving the reliability of the cleaning equipment and further improving the user experience.

[0095] In some embodiments, the airflow driving member 3 can define a transition flow channel, two ends of the transition flow channel being in communication with the first dust collection cavity 12 and the second dust collection cavity 13, for example, the two ends of the transition flow channel being in communication with the dust-gas separation flow channel 122 and the liquid-gas separation flow channel 131. The airflow driving member 3 includes electrical elements, and the electrical elements are isolated from the transition flow channel. In this way, it can be ensured that the airflow driving member 3 smoothly drives the airflow from the side of the first dust collection cavity 12 to the side of the second dust collection cavity 13 via the airflow driving member 3, and at the same time, it can also avoid the water in the airflow from contacting the electrical elements, damaging the electrical elements and affecting the normal operation of the cleaning equipment.

[0096] In some embodiments, the airflow driving member 3 is a dry-wet dual-purpose motor. In this way, it can avoid water entering the inside of the airflow driving member 3, causing damage to the airflow driving member 3, making the airflow driving member 3 more adaptable and more practical, improving the reliability of the cleaning equipment and further improving the user experience.
