Description

Technical Field

[0001] The utility model relates to the technical field of steam cleaning machines, in particular to a cleaning filter component and a steam cleaning machine. Background Art

[0002] At present, steam cleaning machines are cleaning equipment that uses high-temperature steam for cleaning. They are mostly used to clean floor oil stains, kitchen walls, stoves, etc. The dirt is sucked into the sewage tank through the brush head under the action of negative pressure, and then the dirt is separated from the air in the sewage tank, and the air enters the fan after being filtered. In the related art, the filter device is set inside the sewage tank, which is inconvenient for users to clean and maintain, and the filter device is easily soaked by sewage in the sewage tank, affecting the filtering effect. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] In view of this, an embodiment of the first aspect of the utility model provides a cleaning filter assembly.

[0005] The embodiment of the second aspect of the utility model provides a steam cleaning machine.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the first aspect of the utility model provides a cleaning and filtering assembly, including: a sewage separation box, the sewage separation box including a first inlet and a first outlet; a fan, connected to the first outlet of the sewage separation box, the fan runs to form a suction force on the sewage separation box; a connecting pipe, one end of the connecting pipe is connected to the fan, and the other end is connected to the first outlet; a filter element is arranged outside the sewage separation box and is located between the connecting channel between the fan and the sewage separation box, and the connecting channel includes a connecting pipe.

[0007] The cleaning and filtering assembly proposed by the utility model mainly includes a sewage separation box, a fan and a filter element. Specifically, the sewage separation box is used to receive the sewage and air mixture sucked from the cleaning area, realize the separation of sewage and air, keep the sewage in the box, and discharge it through the first outlet. Among them, the first inlet serves as the inlet of the sewage separation box, and is used to receive the gas-liquid mixture sucked from the cleaning area. The first outlet serves as the outlet of the sewage separation box, and is used to discharge the separated sewage, and the gas and a small amount of residual liquid flow to the fan. By connecting the fan with the first outlet of the sewage separation box, it operates to form suction on the sewage separation box, and the gas in the gas-liquid mixture is sucked in and enters through the filter element.

[0008] It should be emphasized that a filter is provided between the connection channel connecting the fan and the sewage separation box, which can filter dirt in the gas-liquid mixture, prevent dirt from entering the inside of the fan, and protect the fan from damage. When the fan is running, the liquid in the gas-liquid mixture flowing in through the first inlet will remain in the sewage separation box, while the gas will flow to the fan through the first outlet and the filter. The function of the filter is to ensure that only clean gas can enter the fan, thereby preventing dirt from entering the inside of the fan and protecting the normal operation of the equipment.

[0009] It can be understood that the connecting channel is arranged between the fan and the sewage separation box, and the connecting pipeline is part of the connecting channel. By arranging the filter in the connecting channel, the dirty substances that flow into the fan can be effectively prevented, thereby ensuring the normal operation of the fan.

[0010] The above combination can effectively prevent dirt from entering the steam cleaner's fan, thus protecting the equipment from damage. At the same time, users can easily maintain the filter system, replace and clean the filter elements without opening the sewage separation tank. This design can improve the reliability and usability of the steam cleaner and extend the service life of the equipment. The placement of the filter system is precisely designed to ensure that it can effectively filter dirt without affecting the normal operation of the equipment. Through our solution, the steam cleaner can perform cleaning work more efficiently and safely, providing users with a better cleaning experience.

[0011] In some technical solutions, optionally, the filter element is arranged in the connecting pipeline; or the filter element is arranged at the first outlet.

[0012] In this technical solution, the connecting pipeline is a channel connecting the sewage separation box and the fan, one end of which is connected to the air inlet of the fan, and the other end is connected to the first outlet of the sewage separation box. In one embodiment, the filter element can be arranged in this connecting pipeline. The connecting pipeline is designed to make the gas flow smooth and easy to disassemble or access for replacement and cleaning of the filter element. In another embodiment, the filter element can be arranged at the first outlet. When the first outlet is a pipe section structure, the filter element can be arranged on the inner side of the first outlet to achieve filtering.

[0013] Furthermore, the filter element may be in the form of filter cotton or filter sheet.

[0014] With this design, when the fan is turned on to generate suction, the gas-liquid mixture will be sucked into the sewage separation box, the liquid part will be separated and retained in the box, and the gas part will flow to the fan through the first outlet and the connecting pipeline. In the process of flowing to the fan, the gas will be cleaned of dirt by the filter element to ensure that only clean gas enters the fan. This not only ensures the operating efficiency and life of the fan, but also avoids secondary pollution of dirt, improving the cleaning effect and reliability of the equipment.

[0015] In some technical solutions, optionally, it also includes: a main inlet pipe, one end of which is connected to the first inlet, and the other end is used to connect to the cleaning brush head.

[0016] In this technical solution, the main inlet pipe is the connecting channel between the cleaning brush head and the sewage separation tank. Its function is to transport the gas-liquid mixture (including dirt and sewage) generated during the cleaning process from the cleaning brush head to the sewage separation tank. The design of the main inlet pipe must ensure that the gas-liquid mixture can flow smoothly and is not easily blocked. The cleaning brush head is located at the other end of the main inlet pipe and directly contacts the surface to be cleaned, such as the floor, kitchen wall or stove. The function of the cleaning brush head is to remove oil and other stains on the surface through physical friction and high-temperature steam.

[0017] The main inlet pipe transports the gas-liquid mixture sucked from the cleaning brush head into this box to separate the liquid and gas. The sewage is retained in the box, while the gas continues to flow to the fan.

[0018] When the steam cleaning machine starts working, the fan generates suction and draws the gas-liquid mixture generated at the cleaning brush head into the sewage separation box through the main inlet pipe. In the sewage separation box, the liquid is separated and retained, while the gas enters the connecting pipeline through the first outlet and is cleaned by the filter element in the process. Finally, the filtered clean gas is discharged by the fan, completing the entire cleaning and filtering cycle.

[0019] This design not only improves the cleaning efficiency of the steam cleaner, but also protects the fan through the filtration system, prolongs the service life of the equipment, and provides users with a more convenient maintenance method. At the same time, through the effective combination of the main inlet pipe and the cleaning brush head, it can ensure that all pollutants generated during the cleaning process are effectively processed, thereby improving the overall cleaning effect.

[0020] In some technical solutions, optionally, the first inlet and the first outlet are in the same plane, and the axis of the first inlet is parallel to the axis of the first outlet.

[0021] In this technical solution, when the first inlet and the first outlet are in the same plane and their axes are parallel, the structure of the sewage separation tank can be simplified, making the entire system more compact and sturdy, reducing the space occupied by the equipment in the vertical direction, and making the equipment easier to adapt to different usage environments and storage conditions.

[0022] At the same time, the parallel axes facilitate the fluidity of the gas-liquid mixture, reducing fluid dynamics resistance, thereby improving suction and discharge efficiency.

[0023] In terms of processing, the above design can make the manufacture of the sewage separation box simpler, because two ports can be processed simultaneously on the same plane, which is also convenient for subsequent maintenance and cleaning.

[0024] In addition, since the first inlet and the first outlet are on the same plane, the flow path of the gas-liquid mixture in the sewage separation tank is more direct, which helps to evenly separate the liquid and the gas, making the separation effect more efficient.

[0025] In some technical solutions, optionally, the sewage separation box specifically includes: a box body; a cover body, which is detachably connected to the box body, and the first inlet and the first outlet are arranged on the cover body.

[0026] In this technical solution, the sewage separation tank includes a tank body and a cover body, and the tank body is the main part for collecting and storing the liquid (i.e., sewage) separated from the gas-liquid mixture sucked from the cleaning area. In addition, the tank body provides the main structural support for the entire sewage separation tank, and is usually designed to be strong enough to withstand the pressure and impact during operation.

[0027] Since the cover is detachably connected to the box, the user can easily open the cover to inspect, clean and maintain the inside. The first inlet and the first outlet are arranged on the cover, and such an integrated design can simplify the pipe connection and also facilitate the maintenance of these components when the cover is opened.

[0028] Among them, when the cover is closed, there is usually a sealing ring or other sealing design at the joint between the cover and the box body to ensure that the gas-liquid mixture does not leak from the joint during operation.

[0029] This design of sewage separation box makes the operation of cleaning the entire filter assembly more efficient and convenient. Users can easily remove the cover to access the inside of the box for cleaning or replacement of components. At the same time, the setting of the inlet and outlet on the cover also simplifies the pipeline layout and reduces the complexity of manufacturing and maintenance.

[0030] The inlet and outlet design on the cover also helps the flow and separation efficiency of the gas-liquid mixture. Since the inlet and outlet are on the cover, the gas has a shorter path when leaving the box, reducing resistance and possible liquid carryover, and improving the separation effect.

[0031] In addition, this design also helps improve the safety performance of the equipment, because users do not have to worry about liquid leakage or contact with contaminants when performing maintenance. Through regular maintenance, the long-term operation of the entire cleaning and filtration assembly can be ensured, while maintaining efficient separation and filtration effects.

[0032] In some technical solutions, optionally, the fan includes: a shell, on which a second inlet is provided, and the second inlet is connected to the first outlet through a pipeline.

[0033] In this technical solution, the design of the fan includes a shell and a second inlet, and the second inlet is connected to the first outlet through a pipeline. The setting of the second inlet can increase the flow speed and suction efficiency of the gas, thereby improving the performance and efficiency of the fan. The second inlet is connected to the first outlet through a pipeline. This connection method can ensure that the gas separated from the sewage separation tank can directly enter the fan, reducing the resistance to gas flow and improving the overall work efficiency. The second inlet can optimize the flow path of the gas inside the fan, so that the gas can pass through the fan more smoothly, reduce energy loss, and improve the suction effect.

[0034] Through the design of the second inlet and the pipeline, the airflow of the entire system can be made smoother, the resistance to gas flow is reduced, and the overall efficiency of cleaning the filter assembly is improved.

[0035] In summary, the design of the fan can effectively improve the suction efficiency and overall performance of the fan through the arrangement of the second inlet and the pipeline, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly.

[0036] In some technical solutions, optionally, a third inlet is provided on the shell, and the second inlet and the third inlet are respectively provided on opposite sides of the shell.

[0037] In this technical solution, a third inlet is provided on the shell, and the second inlet and the third inlet are respectively provided on opposite sides of the shell. By providing the third inlet, the system can increase more gas entering the fan, thereby improving the air flow and suction efficiency.

[0038] The second inlet and the third inlet are respectively located on opposite sides of the shell, which can make the flow path of the gas inside the fan more uniform, thereby improving the overall working efficiency.

[0039] The settings of the second inlet and the third inlet can balance the airflow inside the fan, reduce energy loss, improve the suction effect, and at the same time help reduce noise and vibration.

[0040] By setting the second inlet and the third inlet, the airflow of the entire system can be made more uniform and stable, thereby improving the overall efficiency and cleaning effect of the cleaning filter assembly.

[0041] In summary, by designing the third inlet and the second inlet and the third inlet to be respectively arranged on opposite sides of the shell, the suction efficiency and overall performance of the fan can be effectively improved, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly.

[0042] In some technical solutions, optionally, the shell specifically includes: a first body and a second body connected to each other, the first body and the second body are arranged along the height direction of the sewage separation tank, the first body is provided with a third inlet, and the second body is provided with a second inlet.

[0043] In this technical solution, the housing is composed of a first body and a second body connected to each other, and the two bodies are arranged along the height direction of the sewage separation tank. The first body is provided with a third inlet, and the second body is provided with a second inlet. Since the housing is composed of two connected bodies, the structural stability of the entire fan can be improved, making the fan more solid and reliable when working.

[0044] The third inlet on the first body and the second inlet on the second body can divert the airflow before entering the fan, which is conducive to evenly distributing the airflow and reducing the kinetic energy loss of the airflow. In addition, by setting the third inlet and the second inlet, more gas can be added to the fan, thereby improving the airflow volume and suction efficiency.

[0045] In summary, by arranging the first body and the second body along the height direction of the sewage separation box and respectively arranging the third inlet and the second inlet, the suction efficiency and overall performance of the fan can be effectively improved, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly.

[0046] In some technical solutions, optionally, it also includes: a second outlet, provided on the second body, the second outlet is used to discharge the gas flowing into the fan through the first outlet; a third outlet, provided on the first body, the third outlet is used to discharge the gas flowing into the fan through the third inlet; wherein the second outlet and the third outlet have different directions.

[0047] In this technical solution, the fan also includes a second outlet and a third outlet. The second outlet is provided on the second body to discharge the gas flowing into the fan through the first outlet; and the third outlet is provided on the first body to discharge the gas flowing into the fan through the third inlet. In addition, the second outlet and the third outlet have different directions. The second outlet and the third outlet are provided so that the gas processed by the fan can be discharged from different positions respectively, which is conducive to the rapid discharge and circulation of the gas. Through the provision of the second outlet and the third outlet, the processed gas can be diverted and discharged, which helps to reduce the resistance of gas flow and improve the overall work efficiency.

[0048] By limiting the second outlet and the third outlet to have different directions, the gases can be effectively prevented from interfering with each other, thereby ensuring the smooth discharge of the gases and reducing the eddy currents and resistance that may be generated when the gases are discharged. Of course, by setting the outlets in different directions, the interference when the gases flow out can be reduced, thereby improving the stability and reliability of the entire system.

[0049] In summary, the second outlet and the third outlet can effectively improve the exhaust efficiency and overall performance of the fan, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly. At the same time, the outlets in different directions can also help reduce the resistance of the gas flow and improve the stability and reliability of the entire system.

[0050] The second aspect of the present invention provides a steam cleaning machine, comprising: a cleaning shell; and any one of the cleaning filter components in the first aspect, which is arranged in the cleaning shell.

[0051] According to the steam cleaning machine proposed by the utility model, the cleaning shell can provide an additional protective layer to prevent the cleaning filter assembly from being affected by the external environment and prolong its service life. The cleaning filter assembly is arranged in the cleaning shell, so that the entire steam cleaning machine becomes a whole, which is convenient for installation and movement.

[0052] The cleaning shell can provide a closed environment, making the maintenance and cleaning of the cleaning filter assembly more convenient, while reducing the impact on the surrounding environment. The cleaning shell can prevent the parts of the cleaning filter assembly from being exposed, reducing the risk of accidental damage and improving the safety of the entire device. The cleaning shell can make the appearance of the entire steam cleaning machine neater, and the appearance can be designed as needed, improving the aesthetics of the device.

[0053] In summary, the design of arranging the cleaning filter assembly in the cleaning shell can improve the service life, safety and aesthetics of the entire steam cleaning machine, and also facilitates the maintenance and cleaning of the cleaning filter assembly.

[0054] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0069] Refer to the following Figures 1 to 9 Some embodiments according to the present invention are described.

[0070] like Figure 1 , Figure 8 and Fig. 9As shown, a cleaning and filtering assembly 100 proposed in this embodiment mainly includes a sewage separation box 102, a fan 104 and a filter element 106. Specifically, the sewage separation box 102 is used to receive the sewage and air mixture sucked from the cleaning area, realize the separation of sewage and air, keep the sewage in the box, and discharge it through the first outlet 1024. Among them, the first inlet 1022 serves as the inlet of the sewage separation box 102, and is used to receive the gas-liquid mixture sucked from the cleaning area. The first outlet 1024 serves as the outlet of the sewage separation box 102, and is used to discharge the separated sewage, and the gas and a small amount of residual liquid flow to the fan 104. By connecting the fan 104 with the first outlet 1024 of the sewage separation box 102, the operation is performed to form a suction force on the sewage separation box 102, and the gas in the gas-liquid mixture is sucked in and enters through the filter element 106.

[0071] It should be emphasized that a filter 106 is provided between the connection channel connecting the fan and the sewage separation box, which can filter dirt in the gas-liquid mixture, prevent dirt from entering the inside of the fan 104, and protect the fan 104 from damage. When the fan 104 is running, the liquid in the gas-liquid mixture flowing in through the first inlet 1022 will remain in the sewage separation box 102, while the gas will flow to the fan 104 through the first outlet 1024 and the filter 106. The function of the filter 106 is to ensure that only clean gas can enter the fan 104, thereby preventing dirt from entering the inside of the fan 104 and protecting the normal operation of the equipment.

[0072] It can be understood that the connecting channel is arranged between the fan and the sewage separation box, and the connecting pipeline is part of the connecting channel. By arranging the filter in the connecting channel, the dirty substances that flow into the fan can be effectively prevented, thereby ensuring the normal operation of the fan.

[0073] Through the above combination, dirt can be effectively prevented from entering the fan 104 of the steam cleaning machine, thereby protecting the equipment from damage. At the same time, the user can easily maintain the filter system, replace and clean the filter element 106 without opening the sewage separation box 102. Such a design can improve the reliability and usability of the steam cleaning machine and extend the service life of the equipment. The placement of the filter system is precisely designed to ensure that it can effectively filter dirt without affecting the normal operation of the equipment. Through our solution, the steam cleaning machine can perform cleaning work more efficiently and safely, providing users with a better cleaning experience.

[0074] In some embodiments, the connecting pipe 108 is optionally a passage connecting the sewage separation tank 102 and the fan 104, one end of which is connected to the air inlet of the fan 104, and the other end of which is connected to the first outlet 1024 of the sewage separation tank 102. In one embodiment, the filter element 106 can be arranged in this connecting pipe 108. The connecting pipe 108 is designed to make the gas flow smooth and to be easily disassembled or accessed for replacement and cleaning of the filter element 106. In another embodiment, the filter element can be arranged at the first outlet, and when the first outlet is a pipe section structure, the filter element can be arranged on the inner side of the first outlet to achieve filtering.

[0075] Furthermore, the filter element may be in the form of filter cotton or filter sheet.

[0076] With this design, when the fan 104 is turned on to generate suction, the gas-liquid mixture will be sucked into the sewage separation box 102, the liquid part will be separated and retained in the box, and the gas part will flow to the fan 104 through the first outlet 1024 and the connecting pipe 108. In the process of flowing to the fan 104, the gas will be cleaned of dirt by the filter element 106, ensuring that only clean gas enters the fan 104. This not only ensures the operating efficiency and life of the fan 104, but also avoids secondary pollution of dirt, thereby improving the cleaning effect and reliability of the equipment.

[0077] In some embodiments, optionally, the main inlet pipe 110 is a connecting channel between the cleaning brush head and the sewage separation box 102, and its function is to transport the gas-liquid mixture (including dirt and sewage) generated during the cleaning process from the cleaning brush head to the sewage separation box 102. The design of the main inlet pipe 110 must ensure that the gas-liquid mixture can flow smoothly and is not easily blocked. The cleaning brush head is located at the other end of the main inlet pipe 110 and directly contacts the surface to be cleaned, such as the floor, kitchen wall or stove. The function of the cleaning brush head is to remove oil and other stains on the surface through physical friction and high-temperature steam.

[0078] The main inlet pipe 110 delivers the gas-liquid mixture sucked from the cleaning brush head to the box 1032 to separate the liquid and gas. The sewage is retained in the box, while the gas continues to flow to the fan 104.

[0079] When the steam cleaning machine starts working, the fan 104 generates suction force and sucks the gas-liquid mixture generated at the cleaning brush head into the sewage separation tank 102 through the main inlet pipe 110. In the sewage separation tank 102, the liquid is separated and retained, while the gas enters the connecting pipeline 108 through the first outlet 1024 and is cleaned by the filter element 106 during the process. Finally, the filtered clean gas is discharged by the fan 104, completing the entire cleaning and filtering cycle.

[0080] This design not only improves the cleaning efficiency of the steam cleaning machine, but also protects the fan 104 through the filtering system, prolongs the service life of the equipment, and provides a more convenient maintenance method for users. At the same time, through the effective combination of the main inlet pipe 110 and the cleaning brush head, it can ensure that all pollutants generated during the cleaning process are effectively processed, thereby improving the overall cleaning effect.

[0081] In some embodiments, optionally, Figure 2 and Figure 3 As shown, when the first inlet 1022 and the first outlet 1024 are in the same plane and their axes are parallel, the structure of the sewage separation tank 102 can be simplified, making the entire system more compact and sturdy, and reducing the space occupied by the equipment in the vertical direction, making the equipment easier to adapt to different usage environments and storage conditions.

[0082] At the same time, the parallel axes facilitate the fluidity of the gas-liquid mixture, reducing fluid dynamics resistance, thereby improving suction and discharge efficiency.

[0083] In terms of processing, the above design can make the manufacture of the sewage separation box 102 simpler, because two ports can be processed simultaneously on the same plane, which is also convenient for subsequent maintenance and cleaning.

[0084] In addition, since the first inlet 1022 and the first outlet 1024 are on the same plane, the flow path of the gas-liquid mixture in the sewage separation box 102 is more direct, which helps to evenly separate the liquid and the gas, making the separation effect more efficient.

[0085] In some embodiments, optionally, Figure 2 As shown, the sewage separation box 102 includes a box body 1032 and a cover body 1034. The box body 1032 is the main part for collecting and storing the liquid (i.e., sewage) separated from the gas-liquid mixture sucked from the cleaning area. In addition, the box body 1032 provides the main structural support of the entire sewage separation box 102, and is usually designed to be strong enough to withstand the pressure and impact during operation.

[0086] Since the cover 1034 is detachably connected to the box 1032, the user can easily open the cover 1034 to inspect, clean and maintain the interior. The first inlet 1022 and the first outlet 1024 are arranged on the cover 1034. Such an integrated design can simplify the pipe connection and also facilitate the maintenance of these components when the cover 1034 is opened.

[0087] When the cover 1034 is closed, there is usually a sealing ring or other sealing design at the joint with the box body 1032 to ensure that the gas-liquid mixture does not leak from the joint during operation.

[0088] The sewage separation box 102 of this design makes the operation of the entire cleaning and filtering assembly 100 more efficient and convenient. The user can easily remove the cover 1034 to access the inside of the box 1032 for cleaning or replacement of components. At the same time, the inlet and outlet are arranged on the cover 1034, which simplifies the pipeline layout and reduces the complexity of manufacturing and maintenance.

[0089] The inlet and outlet design on the cover 1034 also contributes to the flow and separation efficiency of the gas-liquid mixture. Since the inlet and outlet are on the cover 1034, the path of the gas when leaving the box 1032 is shorter, reducing resistance and possible liquid carryover, and improving the separation effect.

[0090] In addition, this design is also conducive to improving the safety performance of the equipment, because the user does not have to worry about liquid leakage or contact with pollutants during maintenance. Through regular maintenance, the long-term operation of the entire cleaning and filtering assembly 100 can be ensured while maintaining efficient separation and filtering effects.

[0091] In some embodiments, optionally, the design of the fan 104 includes a housing 1042 and a second inlet 1043, and the second inlet 1043 is connected to the first outlet 1024 through a pipeline. The setting of the second inlet 1043 can increase the flow speed and suction efficiency of the gas, thereby improving the performance and efficiency of the fan 104. The second inlet 1043 is connected to the first outlet 1024 through a pipeline. This connection method can ensure that the gas separated from the sewage separation box 102 can directly enter the fan 104, reducing the resistance to gas flow and improving the overall work efficiency. The second inlet 1043 can optimize the flow path of the gas inside the fan 104, so that the gas can pass through the fan 104 more smoothly, reduce energy loss, and improve the suction effect.

[0092] Through the design of the second inlet 1043 and the pipeline, the airflow of the entire system can be made smoother, the resistance to gas flow is reduced, and the overall efficiency of cleaning the filter assembly 100 is improved.

[0093] In summary, the design of the fan 104 can effectively improve the suction efficiency and overall performance of the fan 104 through the arrangement of the second inlet 1043 and the pipeline, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly 100.

[0094] In some embodiments, optionally, Figure 4 As shown, a third inlet 1044 is provided on the shell 1042, and the second inlet 1043 and the third inlet 1044 are respectively provided on opposite sides of the shell 1042. By providing the third inlet 1044, the system can increase more gas to enter the fan 104, thereby improving the air flow and suction efficiency.

[0095] The second inlet 1043 and the third inlet 1044 are respectively located on opposite sides of the housing 1042 , which can make the flow path of the gas inside the fan 104 more uniform, thereby improving the overall working efficiency.

[0096] The arrangement of the second inlet 1043 and the third inlet 1044 can balance the airflow inside the fan 104, reduce energy loss, improve the suction effect, and help reduce noise and vibration.

[0097] By providing the second inlet 1043 and the third inlet 1044 , the airflow of the entire system can be made more uniform and stable, thereby improving the overall efficiency and cleaning effect of the cleaning filter assembly 100 .

[0098] In summary, by designing the third inlet 1044 and the second inlet 1043 and the third inlet 1044 to be respectively arranged on opposite sides of the shell 1042, the suction efficiency and overall performance of the fan 104 can be effectively improved, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly 100.

[0099] In some embodiments, optionally, Figure 4 As shown, the housing 1042 is composed of a first body 1052 and a second body 1054 connected to each other, and the two bodies are arranged along the height direction of the sewage separation tank 102. The first body 1052 is provided with a third inlet 1044, and the second body 1054 is provided with a second inlet 1043. Since the housing 1042 is composed of two connected bodies, the structural stability of the entire fan 104 can be improved, making the fan 104 more solid and reliable when working.

[0100] The third inlet 1044 on the first body 1052 and the second inlet 1043 on the second body 1054 can divert the airflow before entering the fan 104, which is beneficial to evenly distribute the airflow and reduce the kinetic energy loss of the airflow. In addition, by providing the third inlet 1044 and the second inlet 1043, more gas can be added to enter the fan 104, thereby improving the airflow volume and suction efficiency.

[0101] In summary, by arranging the first body 1052 and the second body 1054 along the height direction of the sewage separation box 102 and respectively arranging the third inlet 1044 and the second inlet 1043, the suction efficiency and overall performance of the fan 104 can be effectively improved, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly 100.

[0102] In some embodiments, optionally, Figure 4As shown, the fan 104 also includes a second outlet 1055 and a third outlet 1053. The second outlet 1055 is provided on the second body 1054, and is used to discharge the gas flowing into the fan 104 through the first outlet 1024; and the third outlet 1053 is provided on the first body 1052, and is used to discharge the gas flowing into the fan 104 through the third inlet 1044. In addition, the second outlet 1055 and the third outlet 1053 have different directions. The second outlet 1055 and the third outlet 1053 are provided so that the gas processed by the fan 104 can be discharged from different positions respectively, which is conducive to the rapid discharge and circulation of the gas. Through the provision of the second outlet 1055 and the third outlet 1053, the processed gas can be diverted and discharged, which helps to reduce the resistance of gas flow and improve the overall work efficiency.

[0103] By limiting the second outlet 1055 and the third outlet 1053 to have different directions, the gases can be effectively prevented from interfering with each other, thereby ensuring the smooth discharge of the gases and reducing the eddy currents and resistance that may be generated when the gases are discharged. Of course, by setting the outlets in different directions, the interference when the gases flow out can be reduced, thereby improving the stability and reliability of the entire system.

[0104] In summary, the second outlet 1055 and the third outlet 1053 are provided to effectively improve the exhaust efficiency and overall performance of the fan 104, thereby improving the working efficiency and cleaning effect of the cleaning filter assembly 100. At the same time, the outlets in different directions are also helpful in reducing the resistance during gas flow, thereby improving the stability and reliability of the entire system.

[0105] The present application proposes another steam cleaning machine 200, such as Figure 5 , Figure 6 and Figure 7 As shown, the cleaning housing 202 can provide an additional protective layer to prevent the cleaning filter assembly 100 from being affected by the external environment and extend its service life. The cleaning filter assembly 100 is arranged in the cleaning housing 202, so that the entire steam cleaning machine 200 becomes a whole, which is convenient for installation and movement.

[0106] The cleaning housing 202 can provide a closed environment, making the maintenance and cleaning of the cleaning filter assembly 100 more convenient, while reducing the impact on the surrounding environment. The cleaning housing 202 can prevent the parts of the cleaning filter assembly 100 from being exposed, reducing the risk of accidental damage and improving the safety of the entire device. The cleaning housing 202 can make the appearance of the entire steam cleaning machine 200 more neat, and the appearance can be designed as needed, thereby improving the aesthetics of the device.

[0107] In summary, the design of arranging the cleaning filter assembly 100 in the cleaning shell 202 can improve the service life, safety and aesthetics of the entire steam cleaning machine 200, and also facilitates the maintenance and cleaning of the cleaning filter assembly 100.

[0108] In a specific embodiment, a steam cleaning machine is proposed, which can filter the air intake of the steam cleaning machine to prevent dirt from being sucked into the fan and damaging the equipment. It should be added that the solution does not require opening the sewage tank to maintain the filtration system, which is convenient for users to replace, clean and maintain the filter cotton / HEPA filter layer. Specifically, the steam cleaning machine includes a cleaning machine body (i.e., a cleaning shell), a sewage tank assembly (i.e., a sewage separation tank), a filter cotton / HEPA filter layer (i.e., a filter element), a hose assembly, and a fan assembly.

[0109] Place the filter cotton / HEPA filter layer above the fan air inlet end of the hose assembly of the cleaning machine body, and then place the sewage tank. First, the fan assembly forms a negative pressure source in the equipment. Under the action of negative pressure, the dirt on the ground passes through the hose assembly and the sewage inlet end into the sewage tank assembly. In the sewage tank, the sewage is separated from the air and remains in the sewage tank. The air enters the hose again through the fan air inlet end and enters the fan assembly after being filtered by the filter cotton / HEPA filter layer.

[0110] According to the cleaning filter assembly and steam cleaning machine provided by the utility model, under the action of the filter element, it is ensured that only clean gas can enter the fan, thereby preventing dirt from entering the inside of the fan and protecting the normal operation of the equipment.
