In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0057] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0058] Please refer to the following Figures 1-11 The present invention will now be described with reference to a filter device 100 of a cleaning device 1000. This filter device 100 is used to filter the wash water of the cleaning device 1000 to remove debris and improve the cleanliness of the wash water. The filtered wash water can be used for circulating washing or for other purposes, such as irrigation, thereby increasing the utilization rate of the wash water.

[0059] According to the filter device 100 of the cleaning device 1000 of the embodiment of the present invention, Figure 1 , including: a structural body 10, which is the main structure of the filter device 100, and bears the support and protection functions, and provides a closed filtering environment for the washing water.

[0060] Reference Figure 2 and Figure 3 , a slag collecting cavity 11 is provided in the structural main body 10. Figure 6 As shown, the slag collecting chamber 11 has a slag collecting inlet 111 and a slag collecting outlet 113. The water flow drives the residue into the slag collecting chamber 11 from the slag collecting inlet 111. After being treated in a certain way, the residue in the water can be gradually separated. The separated residue is stored and accumulated in the slag collecting chamber 11, and then the residue can be discharged from the slag collecting outlet 113 at the appropriate time.

[0061] In this application, there is no limitation on the method of separating washing water and residue in the residue collecting chamber 11. For example, after the residue is driven into the residue collecting chamber 11 by water flow, it will settle for a period of time and the residue and water will automatically separate under the action of gravity. The residue will remain in the bottom layer and the washing water will remain in the upper layer. At this time, the washing water in the upper layer will be pumped out, and the residue with reduced water content will be stored in the residue collecting chamber 11. For example, Figure 6 As shown, a slag filter 20 is provided on the flow path from the slag inlet 111 to the slag outlet 113 in the slag collecting chamber 11 . During the flow, the washing water is gradually filtered out by the slag filter 20 , and the remaining residue with reduced water content remains in the slag collecting chamber 11 .

[0062] In some embodiments, as Figure 2 As shown, the slag collecting chamber 11 has a slag collecting outlet 112. Figure 4As shown, the filtering device 100 also includes: a slag collection filter 20. The slag collection filter 20 is located in the slag collection chamber 11 and is provided at the slag collection outlet 112. The slag collection filter 20 is used to filter the water flowing to the slag collection outlet 112, leaving the residue in the slag collection chamber 11. In this way, after being filtered by the slag collection filter 20, the clean washing water can be discharged from the slag collection outlet 112. After being discharged, the washing water can be recycled or directly discharged. Here, the washing water in the residue is filtered out of the slag collection chamber 11 so that only the residue can be contained. On the one hand, the volume required for residue storage is reduced, so that more residue can be accumulated in the slag collection chamber 11. On the other hand, the residue is almost solid and is concentrated in the slag collection chamber 11, which is more convenient for subsequent processing. For example, when manual slag discharge is required, it is relatively easy to collect and dig out the residue. Moreover, if the washing water filtered in the slag collection chamber 11 can be recycled, the utilization rate of washing water can also be improved, and the water consumption of the cleaning equipment 1000 can be reduced.

[0063] In some embodiments, as Figure 6 As shown, the filtering device 100 further includes a slag discharge valve 61, which is provided at the slag collection outlet 113. By closing the slag collection outlet 113 through the slag discharge valve 61, on the one hand, the slag collection outlet 113 can be set lower in the slag collection chamber 11, and even the slag collection outlet 113 can be set at the lowest point of the slag collection chamber 11, for example, it can be set at the lowest point of the bottom wall surface S1 of the slag collection chamber 11, or at the lowest point of the side wall surface S2 of the slag collection chamber 11, so that it helps to empty the residue in the slag collection chamber 11 during slag discharge. On the other hand, the slag discharge valve 61 can close the slag collection outlet 113 when slag discharge is not required, so that the residue can be allowed to stand and fully separate the liquid and solid after entering the slag collection chamber 11, so as to filter out more washing water.

[0064] In the present application, the structure of the slag discharge valve 61 is not limited and can be an electromagnetic switch valve or other types of valves.

[0065] In some specific embodiments, Figure 6 As shown, the slag discharge valve 61 is a one-way valve 61a that opens outward from the slag collecting chamber 11 in one direction. The opening and closing of the one-way valve 61a is controlled by the pressure differential across the two sides. In other words, the opening and closing of the one-way valve 61a does not require a separate power component, saving the cost of power components. Furthermore, the one-way valve 61a itself generally has a simple structure, making it easy to assemble and reducing its occupied volume, facilitating a compact layout of the filtration device 100.

[0066] Specifically, if Figure 8 As shown, when a one-way valve 61a is set at the slag collection outlet 113, a slag collection water outlet 112 and a slag collection filter 20 are also set in the slag collection water outlet 112. This can reduce the pressure exerted by the washing water on the one-way valve 61a, and avoid the situation where the one-way valve 61a is not closed tightly and is accidentally opened.

[0067] In some specific embodiments, Figure 9 and Figure 10 As shown, the one-way valve 61a includes a bracket 611 and a valve cover 612. The bracket 611 is provided with a through valve port 6113. The bracket 611 is installed at the slag collection and discharge port 113. The valve cover 612 is located on the side of the bracket 611 away from the slag collection chamber 11 and is used to cover the valve port 6113. One end of the valve cover 612 is connected to the bracket 611. This allows the one-way valve 61a to control the opening and closing of the valve port 6113 by the intensity of the air pressure acting on both sides of the valve cover 612. Specifically, when the air pressure inside the slag collection chamber 11 is lower than the air pressure outside the slag collection and discharge port 113, the valve cover 612 is sucked into the valve port 6113 and remains closed. When the air pressure inside the slag collection chamber 11 is higher than the air pressure outside the slag collection and discharge port 113, the valve cover 612 is pushed open to open the valve port 6113. Here, the outside of the slag collecting and discharging port 113 refers to the side of the one-way valve 61a that is away from the slag collecting chamber 11. Figure 10 The air pressure in the middle water collecting chamber 14 is the external air pressure of the slag collecting and discharging port 113 .

[0068] This one-way valve 61a is in the shape of a thin sheet as a whole, does not occupy too much space, is easy to open and close, and is not easily blocked, resulting in an inability to close or open.

[0069] Specifically, the valve cover 612 is a soft cover. In its natural state, the valve cover 612 fits in the valve port 6113, that is, when there is no pressure difference between the interior of the slag collecting chamber 11 and the exterior of the slag collecting and discharging outlet 113, the valve cover 612 fits in the valve port 6113. In this way, when the air pressure inside the slag collecting chamber 11 is lower than the air pressure outside the slag collecting and discharging outlet 113, the valve cover 612 can quickly find the valve port 6113 and close the valve port 6113.

[0070] Specifically, if Figure 10 As shown, the upper end of the valve cover 612 is connected to the bracket 611 , which helps the valve cover 612 to sag under the action of gravity in a natural state to fit in the valve port 6113 .

[0071] Specifically, when the bracket 611 is provided with a through valve port 6113 and the valve cover 612 opens the valve port 6113 , the valve port 6113 is in a fully open state, and the area of ​​the valve port 6113 is the flow area of ​​the slag collecting and discharging port 113 .

[0072] In some specific embodiments, Figure 10 As shown, the bracket 611 is provided with a socket 6114, and the valve cover 612 is provided with a plug 6125, which is assembled in the socket 6114. Alternatively, the bracket 611 is provided with a plug 6125, and the valve cover 612 is provided with a socket 6114, and the plug 6125 is assembled in the socket 6114. This facilitates assembly and disassembly for cleaning.

[0073] Specifically, the insertion hole 6114 is located above the valve port 6113, so that the connection position between the bracket 611 and the valve cover 612 is located above the valve port 6113. This is conducive to the valve cover 612 being fitted at the valve port 6113 when it droops under the action of gravity in a natural state.

[0074] Furthermore, if Figure 10 As shown, the valve cover 612 is provided with an inserting post 6125, and the end of the inserting post 6125 is an expansion block 6127 to achieve positioning.

[0075] In some embodiments, as Figure 10 As shown, the valve cover 612 is provided with a wire groove 6126, which is located between the plug post 6125 and the valve port 6113. The wire groove 6126 is a stress-weakened point on the valve cover 612. When the air pressure inside the slag collecting chamber 11 is higher than the air pressure outside the slag collecting and slag discharging port 113, the valve cover 612 needs to be pushed open to open the valve port 6113. The valve cover 612 can be bent at the wire groove 6126 to facilitate opening the valve port 6113. Optionally, the wire groove 6126 is a transverse through-groove.

[0076] Specifically, if Figure 10 As shown, a positioning rib 6117 is provided on the side of the bracket 611 facing the valve cover 612. The positioning rib 6117 is located in the wire groove 6126. In this way, when the air pressure inside the slag collecting chamber 11 is lower than the air pressure outside the slag collecting and slag discharging port 113, the valve cover 612 can be quickly and accurately closed at the valve port 6113 by inserting the positioning rib 6117 into the wire groove 6126 when the valve cover 612 is sucked.

[0077] Specifically, the valve cover 612 is a soft rubber sheet, so that the valve cover 612 can not only be opened and closed repeatedly, but also is not easily broken by repeated bending, and has a long service life.

[0078] Optionally, the valve cover 612 and the plug 6125 are integrally molded, facilitating processing and reducing the risk of breakage. Furthermore, the valve cover 612 is a soft plastic sheet, and the valve cover 612, the plug 6125, and the expansion block 6127 are all integrally molded. The plug 6215 is a hollow tube with an open end facing the expansion block 6127, facilitating extrusion and deformation for assembly.

[0079] In some embodiments, as Figure 10 As shown, the one-way valve 61a further includes a reinforcing cover plate 613, which is provided on a soft plastic sheet and is positioned directly opposite the valve port 6113. This can improve the strength of the valve cover 612 at the valve port 6113, thereby preventing the valve cover 612 from being deformed by excessive suction when the air pressure inside the slag collecting chamber 11 is too low relative to the air pressure outside the slag collecting and discharging port 113, thereby preventing excessive deformation from causing the valve port 6113 to be unable to be closed.

[0080] Specifically, if Figure 10 As shown, the valve cover 612 is provided with a cover groove 6122, and the reinforcement cover plate 613 is fitted into the cover groove 6122. Furthermore, the reinforcement cover plate 613 is interference-fitted into the cover groove 6122, thereby clamping the reinforcement cover plate 613.

[0081] Specifically, an open cover groove 6122 is formed on the side of the valve cover 612 that is away from the slag collecting chamber 11, facilitating assembly. Furthermore, this side is not directly exposed to water flow or debris, reducing the risk of the reinforced cover plate 613 falling off the valve cover 612. The opening area of ​​the cover groove 6122 is smaller than the corresponding area of ​​the reinforced cover plate 613, allowing the valve cover 612 to wrap around the reinforced cover plate 613 to prevent it from falling off.

[0082] Alternatively, as Figure 10 As shown, the valve cover 612 is formed with a positioning protrusion 6121 on the side facing the slag collecting chamber 11. The positioning protrusion 6121 is used to be inserted into the valve port 6113 when the valve cover 612 is closed, thereby improving the firmness and sealing performance when closed.

[0083] Further optionally, the positioning protrusion 6121 and the valve opening 6113 have the same shape. For example, the positioning protrusion 6121 and the valve opening 6113 may both be semicircular.

[0084] In some specific embodiments, Figure 10 As shown, the filter device 100 further includes a first sealing ring 614, which is positioned over the bracket 611 and is configured to seal the edge of the bracket 611 against the inner wall of the slag collection and discharge port 113. The first sealing ring 614 also helps secure the bracket 611 to the slag collection and discharge port 113, preventing it from being knocked over by pressure differential forces or the impact of residual slag during slag discharge.

[0085] In some embodiments, as Figure 6 As shown, the bottom wall surface S1 of the slag collecting chamber 11 includes a guide bottom surface S11, which gradually decreases in height from the slag collecting inlet 111 to the slag collecting outlet 113. In this way, the residue entering the slag collecting chamber 11 from the slag collecting inlet 111 can be guided by the guide bottom surface S11 to the slag collecting outlet 113, thereby improving the concentration of the residue and facilitating the centralized separation of washing water and the discharge of the residue.

[0086] Specifically, the inclination angle α of the diversion bottom surface S11 is at least 5°. It is understood that residue, especially food residue, has a certain degree of adhesion. Setting the inclination angle α of the diversion bottom surface S11 to at least 5° allows the forces of gravity and water flow acting on the residue to overcome the adhesion to the diversion bottom surface S11. This allows the residue to slide quickly along the bottom of the residue collecting chamber 11, reducing the amount of residue that adheres to the diversion bottom surface S11.

[0087] In some embodiments, the bottom wall S1 of the slag collecting chamber 11 further includes a sunken concave surface S12, one end of which is connected to the lowest edge of the diversion bottom surface S11, and the height of the sunken concave surface S12 gradually decreases toward the diversion bottom surface S11. This configuration forms a downward depression at the connection between the sunken concave surface S12 and the diversion bottom surface S11, which can concentrate residue within the depression and provide a certain capacity. Forming the depression here, rather than adjacent to the side wall S2 of the slag collecting chamber 11, can prevent residue from accumulating in corners to a limited extent, thereby facilitating residue discharge.

[0088] Specifically, the slag collection outlet 113 is located on the sidewall surface S2 of the slag collection chamber 11 and is arranged at the connection between the sunken concave surface S12 and the guide bottom surface S11. This helps to discharge the residue collected on the sunken concave surface S12 from the slag collection outlet 113 in a centralized manner, thereby reducing the amount of residue retained in the slag collection chamber 11.

[0089] Specifically, at least part of the lower edge of the slag collecting and discharging port 113 coincides with the intersection of the sunken concave surface S12 and the side wall surface S2 of the slag collecting chamber 11. This not only facilitates the processing of the slag collecting and discharging port 113, but also facilitates the smooth discharge of residue along the slag collecting and discharging port 113, avoiding the situation where there are steps at the slag collecting and discharging port 113 causing residue to be retained.

[0090] More specifically, the intersection of the sunken concave surface S12 and the sidewall surface S2 of the slag collecting chamber 11 includes a lower concave line S1-2, which coincides with the lower edge of the slag collecting and discharging port 113. The lowest point in the middle of the lower concave line S1-2 is also the lowest point in the slag collecting chamber 11, which facilitates smooth slag discharge.

[0091] Specifically, the guide bottom surface S11 is an inclined surface, the highest side of the guide bottom surface S11 is arranged corresponding to the slag collection inlet 111, and the lowest side of the guide bottom surface S11 is arranged corresponding to the slag collection outlet 113.

[0092] Specifically, the sunken concave surface S12 is an arc-shaped surface. Optionally, the concave line S1-2 at the intersection of the sunken concave surface S12 and the side wall surface S2 of the slag collecting chamber 11 is an arc line. Further optionally, the central angle of the concave line S1-2 is at least 90 degrees.

[0093] The lateral distance from the highest edge to the lowest edge of the sunken concave surface S12 is much smaller than the lateral distance from the highest edge to the lowest edge of the guide bottom surface S11.

[0094] In some specific embodiments, the height difference of the guide bottom surface S11 is at least 5% of the height of the slag collecting chamber 11 .

[0095] It's understandable that the larger size of the slag collecting chamber 11 is designed, on the one hand, to hold wash water during high water flow rates and provide ample space for separating wash water from debris. Setting the height difference between the lowest point of the concave surface S12 and the lowest edge of the diversion bottom surface S11 to at least 5% of the height of the slag collecting chamber 11 not only provides ample centralized space for debris storage, but also creates a shape that's wider at the top and narrower at the bottom, allowing for faster flow rates in the upper, high-residue areas and less debris in the lower, low-flow areas. This facilitates the emptying of debris.

[0096] Optionally, the height difference of the guide bottom surface S11 may be 5%, 6%, 7%, 8%, 9%, 10%, 11%, etc., of the height of the slag collecting chamber 11. Typically, the height difference of the guide bottom surface S11 will not exceed 20% of the height of the slag collecting chamber 11. This avoids the slag collecting chamber 11 being too high, which in turn causes the entire filtration device 100 to be too high.

[0097] In some embodiments, as Figure 2 and Figure 4 As shown, the filter device 100 further includes a slag collection spoiler 22, which is disposed within the slag collection chamber 11 and is adapted to agitate the filtered residue. This arrangement promotes water flow, helps prevent residue from settling to the bottom and then clinging to the wall, and facilitates the collection and discharge of the residue toward the slag collection outlet 113.

[0098] In particular, the debris that settles to the bottom tends to push the water upward, causing the residue to become dry and hard and stick to the bottom wall S1. The arrangement of the debris collection spoiler 22 allows the bottom debris to mix with the wash water above, so that the wash water can carry away the debris as it flows, thereby helping the debris to be concentrated toward the debris collection outlet 113.

[0099] Here, the structural form of the slag collecting and spoiling member 22 is not limited. The slag collecting and spoiling member 22 may be a fixed member in the slag collecting cavity 11 , or a movable member in the slag collecting cavity 11 .

[0100] In some specific embodiments, the slag collection spoiler 22 is a movable part, and is configured to be moved by the flow of water. In other words, the impact of the water flow pushes the slag collection spoiler 22 to move, and the movable slag collection spoiler 22 can stir the filter residue. The stirring action of the slag collection spoiler 22 utilizes the kinetic energy of the water flow, eliminating the need for a separate drive element, thereby reducing the number of parts and improving energy efficiency.

[0101] In other specific embodiments, Figure 5 and Figure 6As shown, the filter device 100 further includes a drive assembly 40, which is connected to the slag collection flow spoiler 22 to drive the movement of the slag collection flow spoiler 22. In other words, the movement of the slag collection flow spoiler 22 is driven by the drive assembly 40. This not only provides high controllability of the movement, but also allows the slag collection flow spoiler 22 to be driven even when the kinetic energy of the water is insufficient. This helps maintain continuous agitation of the filter residue and further reduces the phenomenon of filter residue settling to the bottom and wall.

[0102] In some specific embodiments, the slag collecting spoiler 22 is rotatably disposed in the slag collecting chamber 11, and the driving assembly 40 is used to drive the slag collecting spoiler 22 to rotate. In this way, the structure of the driving assembly 40 is relatively simple, and there is no need to set up an overly complex transmission structure, thereby reducing the occupied space.

[0103] In some specific embodiments, Figure 2 As shown, the slag collecting chamber 11 also has a slag collecting outlet 112, and the filtering device 100 also includes a slag collecting filter 20 provided at the slag collecting outlet 112. At this time, the slag collecting spoiler 22 is located on the side of the slag collecting filter 20 away from the slag collecting outlet 112. It can be understood that the side of the slag collecting filter 20 facing the slag collecting outlet 112 is the side from which the slag collecting filter 20 discharges water, and the side of the slag collecting filter 20 away from the slag collecting outlet 112 is the side where the slag is retained. The slag collecting spoiler 22 is located on the side of the slag collecting filter 20 away from the slag collecting outlet 112, so that the slag collecting spoiler 22 can stir up the residue at the bottom, thereby facilitating the residue to flow to the slag collecting outlet 113, preventing the residue from accumulating around the slag collecting outlet 112 and clogging the slag collecting filter 20, thereby preventing the water carrying the residue from flowing to the slag collecting outlet 112.

[0104] When a slag filter 20 is provided in the slag collecting chamber 11, the slag flow spoiler 22 may be provided on the slag filter 20 or on the inner wall surface of the slag collecting chamber 11, for example, on the bottom wall surface S1 or the side wall surface S2 of the slag collecting chamber 11. Alternatively, there may be multiple slag flow spoilers 22, with some being provided on the slag filter 20 and some being provided on the inner wall surface of the slag collecting chamber 11. This provides a variety of structural options for the slag flow spoilers 22.

[0105] It is understood that because the debris collection spoiler 22 is located on the side of the debris collection filter 20 facing away from the debris collection outlet 112, the debris collection spoiler 22 agitates the debris and also agitates the wash water. When the agitated wash water is flushed onto the debris collection filter 20, it can wash away the debris on the surface of the debris collection filter 20. In other words, the agitated water flow can flush the surface of the debris collection filter 20 on the side where the debris is retained, reducing the possibility of debris clogging the debris collection filter 20 and improving the filtering effect of the debris collection filter 20. This reduces the frequency of replacement and cleaning of the debris collection filter 20.

[0106] In some embodiments, a drive assembly 40 is connected to the slag filter 20 to drive the rotation of the slag filter 20. The drive assembly 40 is used to provide power to drive the slag filter 20 to rotate at high speed. The high-speed rotation of the slag filter 20 generates centrifugal force, so that the residue mixed in the sewage and the residue attached to the slag filter 20 can be separated from the slag filter 20 under the action of centrifugal force, which is conducive to removing the residue clogging the mesh of the slag filter 20.

[0107] It is understandable that conventional filter screens are prone to clogging after being used for a period of time. In order to increase the filtering capacity of the filter screen, the general practice is to increase the filter screen area, but this will increase the cost of the filter screen and increase the space occupied by the filter screen. Another way is to remove the filter screen whenever the filtering effect decreases, and use a scraper to clean the residue blocking the mesh. However, scraper cleaning will squeeze the filter screen, and squeezing the filter screen will affect the performance and life of the filter screen. Moreover, if the filter screen is often squeezed by the scraper, the toughness of the filter screen will decrease. When water flows through the filter screen during use, it is also easy to be squeezed and deformed by the water flow, and the residue blocking the mesh will be clamped off. The broken residue will flow with the water flow to the residue collection outlet, causing secondary pollution and affecting the cleaning effect.

[0108] In the present application, when the driving assembly 40 is provided to drive the slag filter 20 to rotate, the debris stuck on the slag filter 20 can be shaken off, thereby maintaining the filtering effect of the slag filter 20. Moreover, without the scraper squeezing, the service life of the slag filter 20 can be extended, the frequency of cleaning the slag filter 20 can be reduced, the probability of subsequent secondary contamination of the slag filter 20 can be reduced, and the reuse and cleaning effect of the washing water can be improved.

[0109] In some embodiments, when the filter device 100 further includes a rotatable slag filter 20, such as Figure 4 As shown, the slag collection spoiler 22 is provided on the slag collection filter 20, so that the slag collection filter 20 and the slag collection spoiler 22 can be operated simultaneously to achieve linkage. This can simplify the structure and improve compactness.

[0110] For example, when the slag collection spoiler 22 is driven by water flow to rotate, the water flow simultaneously drives the slag collection filter 20 to rotate. This eliminates the need for a separate drive component to drive the slag collection filter 20, saving parts and improving energy efficiency. For another example, when a drive assembly 40 is connected to the slag collection spoiler 22 to drive the slag collection spoiler 22, it can also drive the slag collection filter 20 to rotate.

[0111] Specifically, when the slag collection spoiler 22 is installed on the slag collection filter 20, it is positioned adjacent to the bottom wall surface S1 of the slag collection chamber 11. This allows the slag collection spoiler 22 to perform a dual function: on the one hand, it stirs up sediment at the bottom, preventing it from sticking, and allows it to mix with the wash water and flow downward under the influence of the water flow. On the other hand, even at low water levels, the slag collection spoiler 22 near the bottom can stir up the water flow, allowing it to flow to the surface of the slag collection filter 20, flushing away surface debris, reducing the amount of debris clogging the slag collection filter 20, and extending its service life.

[0112] In some embodiments, as Figure 7 As shown, the slag filter screen 20 includes a first filter cartridge 21, which covers the slag outlet 112 and is provided with a first mesh 211. The arrangement of the first filter cartridge 21 provides the slag filter screen 20 with a larger filtration area, allowing water to flow toward the slag outlet 112 in a 360-degree direction. Furthermore, all water flowing toward the slag outlet 112 must be filtered by the first filter cartridge 21. The first filter cartridge 21 has a simple structure and low manufacturing costs.

[0113] It should be noted that the maximum particle size passing through the slag filter 20 can be limited by the size of the first mesh 211 on the first filter cartridge 21. For example, when the width of the first mesh 211 is set to 0.1 mm, the first filter cartridge 21 can retain residue with a particle size exceeding 0.1 mm in the slag collection chamber 11, while residue with a particle size less than 0.1 mm may flow with the washing water to the slag collection outlet 112. Alternatively, at least one layer of filter cloth can be provided on the surface of the first filter cartridge 21. The first filter cartridge 21 is a rigid member used to support the filter cloth. The maximum particle size passing through the slag filter 20 is limited by the mesh size of the filter cloth.

[0114] like Figure 4 As shown, the debris flow spoiler 22 is connected to the outer circumference of the first filter cartridge 21 to guide water flow around the outer circumference of the first filter cartridge 21. When the debris filter screen 20 is rotatable, the structure of the first filter cartridge 21 ensures that the radial distance between each point on the first filter cartridge 21 and the debris outlet 112 is substantially consistent, thereby achieving consistent centrifugal force and facilitating the balanced removal of debris from all surfaces. Optionally, the first filter cartridge 21 is cylindrical, and when the drive assembly 40 is in operation, the first filter cartridge 21 rotates around the center of the debris outlet 112.

[0115] The debris collection spoiler 22 guides the water flow along the outer peripheral surface of the first filter cartridge 21. The debris collection spoiler 22 lengthens the water flow path along the outer peripheral surface of the first filter cartridge 21, thereby impacting more debris. In addition, the debris collection spoiler 22 can guide the water flow to impact the debris on the first filter cartridge 21 in a tangential direction, making it easier for the debris to be knocked off the first filter cartridge 21. This improves the debris removal and anti-blocking capabilities of the first filter cartridge 21.

[0116] In some specific embodiments, Figure 4 As shown, the slag-collecting spoiler 22 includes a plurality of circumferentially spaced spoiler blades 221, which extend obliquely relative to the rotation axis of the slag filter 20. This allows water flowing on the upper surfaces of the spoiler blades 221 to continue flowing upward along the spoiler blades 221. The rotation of all the spoiler blades 221 forms an upward vortex on the surface of the slag filter 20. This creates a strong vortex, and each stream of water flows more persistently under the influence of each other, enhancing the impact force of the water flow, extending the impact distance of the water flow, and improving the ability to remove filter residue.

[0117] Specifically, if Figure 4 As shown, the upper surface f1 of the slag collection spoiler 221 is an arcuate surface, and the upper end of the slag collection spoiler 221 gradually approaches the horizontal plane, thereby guiding the water flow to rotate circumferentially. In this way, each water flow pushes the water flow on one side circumferentially, and each water flow is pushed by the water flow on the other side circumferentially. All water flows push each other, which helps the water flow maintain swirling power and prolong the rotational flow time, thereby enhancing the impact force of the water flow on the slag collection filter 20 and improving the cleaning ability of the filter residue.

[0118] Furthermore, if Figure 6 As shown, the slag collection spoiler 221 forms a circle at the lower end of the slag collection filter screen 20, rather than multiple circles. In this way, when the water flow is directed upward by the slag collection spoiler 221, it will not encounter another circle of spoilers to cause flow obstruction.

[0119] In some specific embodiments, Figure 6 and Figure 7 As shown, the slag collection filter 20 is arranged vertically, and a slag collection spoiler 22 is provided at the bottom of the slag collection filter 20. In this way, the slag collection spoiler 22 can prevent the residue from sinking to the bottom of the slag collection chamber 11, and also facilitate the slag collection filter 20 to be tall and thin as a whole, thereby reducing the resistance to water flow and reducing the space occupied by the slag collection.

[0120] After such arrangement, when the slag filter 20 is driven to rotate by the driving assembly 40, the driving assembly 40 can be set below or above the slag collecting chamber 11, and can be avoided as much as possible from being set on the side wall surface S2 of the slag collecting chamber 11, so as to avoid the overall occupied area being too large and making it impossible to use in the kitchen.

[0121] Specifically, if Figure 7 As shown, the slag collection outlet 112 is provided on the bottom wall surface S1 of the slag collection chamber 11. The slag collection filter 20 is vertically arranged and covers the slag collection outlet 112. The slag collection filter 20 is higher than the bottom wall surface S1 of the slag collection chamber 11 at least at the mesh point. This not only utilizes the water flow characteristics to allow filtered water to be quickly discharged from the slag collection outlet 112, but also prevents residue from accumulating and clogging the mesh points of the slag collection filter 20.

[0122] In some specific embodiments, Figure 6 and Figure 8 As shown, the structural body 10 includes a platform 114 arranged on the bottom wall surface S1 of the slag collecting chamber 11, the platform 114 is arranged around the slag collecting outlet 112, and the slag collecting filter 20 is arranged on the platform 114 so that the slag collecting filter 20 is higher than the bottom wall surface S1 of the slag collecting chamber 11.

[0123] The platform 114 lifts the slag collection filter screen 20 so that the lower edge of the slag collection filter screen 20 is located on the platform 114. In this way, the gap between the two is higher, preventing the bottom residue from flowing into the slag collection outlet 112 through the gap.

[0124] In some embodiments, as Figure 11 As shown, a slag collecting cleaning port 171 is formed on the structural body 10 and communicates with the slag collecting cavity 11. Figure 7 and Figure 8 As shown, the filter device 100 further includes a slag collecting cover 62, which is openably mounted at the slag collecting cleaning port 171. This allows for easy opening of the slag collecting cover 62 during inspection or cleaning, allowing for observation, cleaning, and maintenance operations from the slag collecting cleaning port 171.

[0125] Here, the slag collecting and cleaning port 171 is located on the top wall of the slag collecting chamber 11 , so that the probability of water leakage is low. Of course, it is not ruled out that in some solutions, the slag collecting and cleaning port 171 is located on the side wall surface S2 of the slag collecting chamber 11 .

[0126] Specifically, the projection of the slag filter 20 on the surface where the slag cleaning port 171 is located is completely located within the slag cleaning port 171, and the slag filter 20 is detachably arranged in the slag collecting cavity 11. This makes it convenient to remove and take out the slag filter 20 from the slag cleaning port 171, thereby improving the convenience of maintenance and cleaning.

[0127] Furthermore, if Figure 11 As shown, the edge of the slag collecting cover 62 is provided with a first screw-lock structure 115 that matches the inner edge of the slag collecting cleaning port 171, so that the slag collecting cover 62 can be rotatably connected to the slag collecting cleaning port 171. When in use, the slag collecting cover 62 is screwed on to prevent it from being washed away by water flow, and the slag collecting cover 62 is screwed off when cleaning.

[0128] In some embodiments, as Figure 7 and Figure 8 As shown, the slag filter 20 is rotatably connected to the slag cover 62 via a first bearing 64. In this way, when the slag cover 62 is set, the slag filter 20 is supported by the slag cover 62 for rotation, which can improve the rotation stability and avoid damage caused by the slag filter 20 swinging during rotation.

[0129] In some embodiments, as Figure 7As shown, the slag cleaning port 171 is arranged opposite to the slag water outlet 112, and the slag filter 20 is arranged at the slag water outlet 112, which is convenient for directly removing the slag filter 20.

[0130] Specifically, the slag collection filter screen 20 is detachably connected to the drive assembly 40, so that when the slag collection cover 62 is opened, the slag collection filter screen 20 can be removed from the drive assembly 40. After maintenance is completed, the slag collection filter screen 20 is installed back on the drive assembly 40.

[0131] Specifically, if Figure 7 and Figure 8 As shown, the drive assembly 40 includes a drive member 41 and a first rotating shaft 42. The first rotating shaft 42 is vertically arranged. One end of the first rotating shaft 42 is connected to the drive member 41 for power, and the other end is connected to the slag collection filter 20. The connection position of the first rotating shaft 42 and the slag collection filter 20 is conveniently set according to the position of the rotation center of the slag collection filter 20.

[0132] Specifically, one end of the first rotating shaft 42 extends into the slag collecting chamber 11 through the slag collecting water outlet 112 , and the first rotating shaft 42 is connected to the slag collecting filter screen 20 , so that the slag collecting filter screen 20 can rotate around the center of the slag collecting water outlet 112 .

[0133] Furthermore, if Figure 7 and Figure 4 As shown, the slag filter 20 also includes a first top cover 23 connected to the top of the first filter cartridge 21, the top cover 23 is covered with a first rotating shaft 42, and the first bearing 64 is fitted between the top cover 23 and the first rotating shaft 42, so that the torsional performance of the slag filter 20 can be improved, the connection reliability is high, and the rotation is more stable.

[0134] In some embodiments, as Figure 2 and Figure 3 As shown, the main body 10 is further provided with a clean water chamber 12 having a clean chamber inlet 121, a clean water outlet 122 and a waste outlet 123. The waste outlet 123 is connected to the slag collection inlet 111. The filter device 100 also includes a clean water filter 30 provided on the clean water outlet 122.

[0135] That is, in the direction of residue flow, the clean water chamber 12 is located upstream of the slag collecting chamber 11. Washing water containing residue enters the clean water chamber 12 from the clean water chamber inlet 121. After being filtered by the clean water filter 30, the filtered washing water is discharged from the clean water outlet 122. The remaining residue containing a certain amount of water is discharged from the waste outlet 123 to the slag collecting chamber 11. Within the slag collecting chamber 11, the residue is further separated and concentrated at the slag collecting outlet 113 before being discharged. This prior filtration by the clean water filter 30 reduces the water content of the residue discharged to the slag collecting chamber 11, facilitating centralized treatment of the residue.

[0136] In some embodiments, the filter device 100 further includes a water flow disruptor (not shown), which is disposed within the water purification chamber 12 and located on the side of the water purification screen 30 facing away from the purified water outlet 122, and is adapted to agitate the water flow. In other words, the water flow disruptor is located upstream of the water purification screen 30 in the direction of purified water flow.

[0137] Specifically, the water flow disturber can stir the flow of water in the water chamber 12, effectively preventing debris from accumulating in the water chamber 12. At the same time, the stirred water flow can flush the surface of the upstream side of the water filter 30 to prevent debris from clogging the water filter 30, thereby improving the filtering effect of the filter device 100. The water flow stirred by the water flow disturber can better drive the debris into the slag collection chamber 11 through the waste outlet 123 for centralized treatment of the debris.

[0138] like Figure 11 As shown, the waste outlet 123 is higher than the bottom wall S6 of the clean water chamber 12. This prevents excessively strong water flow from flowing into the waste outlet 123 without being filtered. Furthermore, with this arrangement, the waste outlet 123 is higher than the clean water outlet 122, preventing water from flowing from the bottom of the clean water chamber 12 from flowing into the clean water outlet 122. This improves the water output of the clean water chamber 12.

[0139] Furthermore, the slag collecting inlet 111 is higher than the bottom wall surface S1 of the slag collecting chamber 11 , which can prevent the residue in the slag collecting chamber 11 from being directly impacted by the water flow and returning to the water purification chamber 12 .

[0140] The provision of the water purification spoiler not only facilitates the automatic discharge of residue from the filter device 100, effectively preventing residue from clogging and accumulating in the water purification chamber 12, but also effectively cleans residue adhering to the upstream surface of the water purification screen 30, preventing clogging of the water purification screen 30 and maintaining the filtration efficiency of the water purification screen 30. Furthermore, the water purification spoiler stirs the flow of water on the upstream side, further improving the filtration effect of residue.

[0141] When a water purification screen 30 is provided in the water purification chamber 12, the water purification flow spoiler can be provided on the water purification screen 30, or on the inner wall surface of the water purification chamber 12, for example, on the bottom wall surface S6 of the water purification chamber 12 or on the side wall surface S5 of the water purification chamber 12. Alternatively, there can be multiple water purification flow spoilers, with some being provided on the water purification screen 30 and some being provided on the inner wall surface of the water purification chamber 12. This provides a variety of water purification flow spoiler structural options for selection.

[0142] The water purification spoiler can also effectively prevent blockage in the water purification chamber 12. When assembling the filter device 100, it is only necessary to ensure that the water purification spoiler is located between the upstream side of the water purification filter 30 and the side wall surface S5 of the water purification chamber 12. Such a position can ensure that the water purification spoiler can stir the water flow on the upstream side of the water purification filter 30.

[0143] When the clean water flow spoiler is protruding from the surface on the upstream side of the clean water filter 30, the clean water flow spoiler can more directly agitate the fluid and residual debris on the upstream side, making it easier for them to enter the slag collecting chamber 11 through the waste outlet 123. The protruding design increases the contact area between the clean water flow spoiler and the fluid, thereby improving the agitation effect.

[0144] When the water purification spoiler protrudes from the inner wall surface of the water purification chamber 12, after the water purification spoiler is reasonably set, it can not only stir the fluid and residue on the upstream side, but also have a certain impact on the fluid flow in the water purification chamber 12, guiding more residue to move toward the waste outlet 123, thereby improving the residue discharge efficiency.

[0145] When the water purification spoiler is located between the upstream side of the water purification screen 30 and the inner wall of the water purification chamber 12, the water purification spoiler can be reasonably designed according to the actual size of the filter device 100, which provides greater flexibility. For example, the filter device 100 can adjust the position, angle, or movement of the water purification spoiler and optimize the water purification spoiler according to different cleaning requirements and usage scenarios to achieve optimal agitation and slag removal effects.

[0146] Specifically, if Figure 3 As shown, the distribution positions of the clean cavity inlet 121 and the waste outlet 123 will affect the separation effect. Distributing the clean cavity inlet 121 and the waste outlet 123 at intervals along the circumference of the clean water cavity 12 can prevent the separated residue from mixing into the water again, and can ensure that the residue is more evenly distributed in the clean water cavity 12 when entering the clean water cavity 12, reducing the situation of excessive or insufficient local distribution, thereby improving the filtration efficiency and filtration effect.

[0147] In some specific embodiments, the water spoiler is a movable part, and is configured to be moved by the flow of water. In other words, the water flow impacts the water spoiler, which in turn stirs the filter residue. The stirring action of the water spoiler utilizes the kinetic energy of the water flow, eliminating the need for a separate drive element. This not only reduces the number of parts but also improves energy efficiency.

[0148] In other embodiments, the filter device 100 further includes a drive assembly 40 connected to the water flow spoiler to drive the water flow spoiler. This not only provides high controllability but also allows the water flow spoiler to be driven even when the kinetic energy of the water is insufficient, thereby maintaining continuous agitation of the filter residue and further reducing the phenomenon of filter residue settling to the bottom or wall.

[0149] In some specific embodiments, the water purification spoiler is rotatably disposed in the water purification chamber 12, and the driving assembly 40 is used to drive the water purification spoiler to rotate. In this way, the structure of the driving assembly 40 is relatively simple.

[0150] In some embodiments, as Figure 7 As shown, the drive assembly 40 is connected to the water purification screen 30 to drive the water purification screen 30 to rotate. The drive assembly 40 is used to provide power to drive the water purification screen 30 to rotate at high speed. The high-speed rotation of the water purification screen 30 generates centrifugal force, so that the residue mixed in the sewage and the residue attached to the water purification screen 30 can be separated from the water purification screen 30 under the action of centrifugal force. This not only facilitates the flow of the residue to the waste outlet 123, but also facilitates the removal of the residue clogging the mesh of the water purification screen 30.

[0151] When the drive assembly 40 is configured to rotate the water purification filter 30, debris stuck on the water purification filter 30 can be shaken off, maintaining the filtering effect of the water purification filter 30. Moreover, without the scraper squeezing, the service life of the water purification filter 30 can be extended, the frequency of cleaning the water purification filter 30 can be reduced, the probability of subsequent secondary contamination of the water purification filter 30 can be reduced, and the reuse and cleaning effect of the washing water can be improved.

[0152] In some embodiments, when the filter device 100 further includes a rotatable water filter 30, the water spoiler is disposed on the water filter 30, so that the water filter 30 and the water spoiler can operate simultaneously, thus achieving linkage. This can simplify the structure and improve compactness.

[0153] Specifically, when the water purification spoiler is installed on the water purification screen 30, it is positioned adjacent to the bottom wall surface S6 of the water purification chamber 12. This allows the water purification spoiler to perform a dual function: on the one hand, it stirs up sediment at the bottom, preventing it from sticking, allowing it to mix with the wash water and flow circumferentially under the influence of the water flow, ultimately reaching the waste outlet 123. On the other hand, when the water level is low, the water purification spoiler near the bottom stirs up the water flow, allowing it to flow onto the surface of the water purification screen 30, flushing away surface debris, reducing the amount of debris clogging the water purification screen 30, and extending its service life.

[0154] In some embodiments, as Figure 7 As shown, the water purification screen 30 includes a second filter cartridge 31, which covers the purified water outlet 122 and is provided with a second mesh 311. The arrangement of the second filter cartridge 31 provides the water purification screen 30 with a larger filtration area, allowing water to flow toward the purified water outlet 122 in a 360-degree direction. Furthermore, all water flowing toward the purified water outlet 122 is filtered by the second filter cartridge 31. The second filter cartridge 31 has a simple structure and low manufacturing cost.

[0155] It should be noted that the maximum particle size passing through the water purification filter 30 can be limited by the size of the second mesh 311 on the second filter cartridge 31. For example, when the width of the second mesh 311 is set at 0.3 mm, the second filter cartridge 31 can leave residues with a particle size exceeding 0.3 mm in the water purification chamber 12, and flow to the waste outlet 123 with the water flow. Residues with a particle size less than 0.3 mm may flow to the water purification outlet 122 with the washing water. Alternatively, at least one layer of filter cloth can be provided on the surface of the second filter cartridge 31, and the second filter cartridge 31 is a rigid part for supporting the filter cloth. The maximum particle size passing through the water purification filter 30 is limited by the mesh size of the filter cloth.

[0156] The purified water flow spoiler is connected to the outer circumference of the second filter cartridge 31 to guide the water flow around the outer circumference of the second filter cartridge 31. When the purified water filter 30 is rotatable, the structure of the second filter cartridge 31 ensures that the radial distance between each point on the second filter cartridge 31 and the purified water outlet 122 is substantially consistent, thereby achieving consistent centrifugal force. Optionally, when the drive assembly 40 is in operation, the second filter cartridge 31 rotates about the center of the purified water outlet 122.

[0157] The water spoiler guides the water flow along the outer circumference of the second filter cartridge 31. The water spoiler lengthens the water flow path along the outer circumference of the second filter cartridge 31, thereby striking more debris. The water spoiler also guides the water flow to strike the debris on the second filter cartridge 31 tangentially, making it easier for the debris to fall off the second filter cartridge 31. This improves the ability to remove debris and prevent blockage of the second filter cartridge 31.

[0158] In some specific embodiments, the water purification spoiler comprises a plurality of circumferentially spaced spoilers, each extending obliquely relative to the rotation axis of the water purification filter 30. This allows water flowing on the upper surface of the spoilers to continue flowing upward along the spoilers. The rotation of all spoilers creates an upward vortex of water on the surface of the water purification filter 30. This creates a strong impact force, and the interaction between individual water streams results in a more sustained flow. This enhances the impact force of the water flow, extends the impact distance of the water flow, and improves the ability to remove filter residue.

[0159] Optionally, the upper surface of the water purification spoiler is an arc-shaped surface, and the upper end of the water purification spoiler gradually approaches the horizontal plane, which can guide the water flow to flow in a circumferential rotation. In this way, each water flow pushes the water flow on one side circumferentially, and each water flow is pushed by the water flow on the other side circumferentially. All water flows push each other, which helps the water flow maintain the swirling power and prolong the rotational flow time, thereby enhancing the impact force of the water flow on the water purification filter 30 and improving the cleaning ability of the filter residue.

[0160] Furthermore, the water purification spoiler forms a circle at the lower end of the water purification filter 30, rather than multiple circles. In this way, when the water flow is directed upward by the water purification spoiler, it will not encounter another circle of spoilers to cause flow obstruction.

[0161] In some embodiments, the water filter 30 is arranged vertically, and a water spoiler is provided at the bottom of the water filter 30. In this way, the water spoiler can prevent residue from sinking to the bottom of the water purification chamber 12, while also making the water filter 30 taller and thinner, thereby reducing resistance to water flow and occupying less space for collecting residue.

[0162] In some embodiments, as Figure 11 As shown, the main body 10 is formed with a clean cavity cleaning port 172 communicating with the clean water cavity 12. Figure 7 and Figure 8 As shown, the filter device 100 further includes a clean cavity cover 63, which is openably mounted at the clean cavity cleaning port 172. This allows for easy opening of the clean cavity cover 63 during inspection or cleaning, allowing for observation, cleaning, and maintenance operations from the clean cavity cleaning port 172.

[0163] Here, the clean cavity cleaning port 172 is located on the top wall of the clean water cavity 12, so that the probability of water leakage is low. Of course, it is not ruled out that in some solutions, the clean cavity cleaning port 172 is located on the side wall surface S5 of the clean water cavity 12.

[0164] Specifically, the projection of the water purification filter 30 on the surface where the clean cavity cleaning port 172 is located is completely located in the clean cavity cleaning port 172, and the water purification filter 30 is detachably arranged in the water purification cavity 12. This makes it convenient to remove and take out the water purification filter 30 from the clean cavity cleaning port 172, thereby improving the convenience of maintenance and cleaning.

[0165] Furthermore, if Figure 11 As shown, the edge of the clean cavity cover 63 and the inner edge of the clean cavity cleaning port 172 are provided with a second screw-lock structure 125 that matches, so that the clean cavity cover 63 can be rotatably connected to the clean cavity cleaning port 172. When in use, the clean cavity cover 63 is screwed on to prevent it from being washed away by water flow, and the clean cavity cover 63 is screwed off when cleaning.

[0166] In some embodiments, as Figure 7 and Figure 8 As shown, the water filter 30 is rotatably connected to the clean chamber cover 63 via a second bearing 68. In this way, when the clean chamber cover 63 is set, the clean chamber cover 63 is used to support the rotation of the water filter 30, which can improve the rotation stability and avoid damage caused by the water filter 30 swinging during rotation.

[0167] In some embodiments, as Figure 7 As shown, the clean cavity cleaning port 172 is arranged opposite to the clean water outlet 122, and the clean water filter 30 is arranged at the clean water outlet 122, which is convenient for directly taking out the clean water filter 30.

[0168] Specifically, the water purification filter 30 is detachably connected to the drive assembly 40, so that when the clean chamber cover 63 is opened, the water purification filter 30 can be removed from the drive assembly 40. After maintenance is completed, the water purification filter 30 is put back on the drive assembly 40.

[0169] Specifically, if Figure 7 and Figure 8 As shown, the drive assembly 40 includes a drive member 41 and a second rotating shaft 43. The second rotating shaft 43 is vertically arranged. One end of the second rotating shaft 43 is connected to the drive member 41 for power, and the other end is connected to the water purification filter 30. In this way, the connection position of the second rotating shaft 43 and the water purification filter 30 can be easily set according to the position of the rotation center of the water purification filter 30.

[0170] Specifically, one end of the second rotating shaft 43 extends into the water purification chamber 12 through the water purification outlet 122 , and the second rotating shaft 43 is connected to the water purification filter 30 , so that the water purification filter 30 can rotate around the center of the water purification outlet 122 .

[0171] Furthermore, if Figure 7 and Figure 4 As shown, the water purification filter 30 also includes a second top cover 33 connected to the top of the second filter cartridge 31, the top cover 33 is covered with a second rotating shaft 43, and the second bearing 68 is fitted between the top cover 33 and the second rotating shaft 43, so that the torsional performance of the water purification filter 30 can be improved, and the connection reliability is high, and the rotation is more stable.

[0172] In some embodiments, the water purification spoiler is linked to the slag collection spoiler 22. In this way, when one of them is driven to move, the other also moves synchronously, which increases the frequency of their activities and enhances the disturbance effect.

[0173] For example, if the water flow in the clean water chamber 12 is large, the clean water spoiler can move under the impact of the water flow, while driving the slag collection spoiler 22. For another example, the driving component 40 drives one of the activities while driving the other activity.

[0174] In some specific embodiments, Figure 7 As shown, both the slag filter 20 and the water purification filter 30 are rotatably mounted on the structural body 10, and the slag filter 20 and the water purification filter 30 are arranged in a linked manner. The drive assembly 40 drives one of them to rotate, while also driving the other to rotate, thus saving one set of drive assemblies 40 and facilitating the arrangement of parts.

[0175] Furthermore, the drive assembly 40 is connected to at least one of the slag filter 20 and the clean water filter 30 to drive the simultaneous rotation of the slag filter 20 and the clean water filter 30. In other words, the slag filter 20 and the clean water filter 30, as well as the clean water spoiler and the slag spoiler 22, are all linked together. A single drive assembly 40 can accomplish all four functions, reducing the number of parts and improving component compactness.

[0176] In some specific embodiments, Figure 7 and Figure 5 As shown, the drive assembly 40 includes a drive member 41, a first rotating shaft 42, and a second rotating shaft 43. One end of the first rotating shaft 42 extends into the slag collection chamber 11 and is connected to the slag collection filter 20. The other end of the first rotating shaft 42 is in dynamic connection with the drive member 41. One end of the second rotating shaft 43 extends into the clean water chamber 12 and is connected to the clean water filter 30. The other end of the second rotating shaft 43 is in dynamic connection with the drive member 41. The two shafts are arranged to connect the two filter screens, resulting in a simple structure and eliminating the need for excessive space.

[0177] In some embodiments, as Figure 1 As shown, the filter device 100 further includes a flow channel plate 50, which is disposed at the bottom of the structural body 10. The driving member 41 is mounted on the flow channel plate 50, which reduces the difficulty of processing and sealing the structural body 10.

[0178] Specifically, if Figure 7 and Figure 8 As shown, the first rotating shaft 42 is vertically arranged, with its upper end extending into the slag collecting chamber 11 through the slag collecting outlet 112. The second rotating shaft 43 is vertically arranged, with its upper end extending into the clean water chamber 12 through the clean water outlet 122. This facilitates the rotation of the slag collecting filter 20 around the center of the slag collecting outlet 112, and the rotation of the clean water filter 30 around the center of the clean water outlet 122.

[0179] In some specific embodiments, Figure 7 and Figure 8 As shown, a gear groove 52 is provided on the flow channel plate 50, and the lower ends of the first rotating shaft 42 and the second rotating shaft 43 both extend into the gear groove 52. The driving assembly 40 also includes: a first gear 44 installed on the first rotating shaft 42, and a second gear 45 installed on the second rotating shaft 43. The first gear 44 and the second gear 45 are meshed with each other, and the driving member 41 cooperates with one of the first gear 44 and the second gear 45. With this arrangement, the gear set for linkage can be arranged in the flat gear groove 52, reducing the overall height dimension. In addition, the gear transmission also facilitates the adjustment of the speed ratio according to the gear ratio, which helps the slag filter 20 and the water purification filter 30 to obtain the appropriate speed.

[0180] In some embodiments, as Figure 7 and Figure 8 As shown, the gear slot 52 is open downward, and the filter device 100 further includes a gear cover 66 fitted on the bottom of the flow channel plate 50. This facilitates assembly, maintenance, and inspection.

[0181] In some embodiments, as Figure 7 and Figure 6As shown, the drive member 41 is a drive motor 41a mounted vertically on the flow channel plate 50. The drive motor 41a is located on the horizontal side of the structural body 10. The lower end of the drive motor 41a is provided with a motor shaft 411 that extends into the gear slot 52. The drive assembly 40 also includes a third gear 46, which is mounted on the motor shaft 411 and meshes with the first gear 44 or the second gear 45. This not only achieves speed reduction and torque increase, but also allows the drive member 41 to be integrated into the horizontal side of the structural body 10, preventing the entire filter device 100 from being too tall.

[0182] In some embodiments, as Figures 1-9 As shown, the filtration device 100 further includes a circulation pump 65. The inlet end 651 of the circulation pump 65 is connected to the slag collection outlet 112. When the circulation pump 65 is in operation, it is used to suck water collected by the slag collection outlet 112 and to create a negative pressure state in the slag collection chamber 11. This allows the slag collection chamber 11 to keep the residue in place under the negative pressure state, and avoids the slag collection inlet 111 from being blocked due to excessive pressure in the slag collection chamber 11.

[0183] In some embodiments, when the filter device 100 includes a circulation pump 65, the inlet end 651 of the circulation pump 65 is also connected to the clean water outlet 122. When the circulation pump 65 is working, it is used to suck water collected in the clean water outlet 122 to complete the circulation of the washing water.

[0184] Specifically, if Figure 8 As shown, when the circulating pump 65 is working, the slag discharge valve 61 closes the slag collection and discharge port 113, and when the circulating pump 65 is shut down, the slag discharge valve 61 opens the slag collection and discharge port 113. In this way, the circulating pump 65 and the slag discharge valve 61 cooperate with each other to achieve automatic slag collection and discharge.

[0185] Specifically, the slag discharge valve 61 is a one-way valve 61a that opens outward from the slag collecting chamber 11. The one-way valve 61a is opened and closed by the pressure difference between the two sides. At this time, the circulating pump 65 is used to control the air pressure inside.

[0186] In some embodiments, as Figure 7 and Figure 8 As shown, a clean water flow channel 51 is provided within the flow channel plate 50, connecting the slag collection outlet 112 and the clean water outlet 122. Here, a single clean water flow channel 51 connects both the slag collection outlet 112 and the clean water outlet 122, reducing the number of flow channels and simplifying the internal structure of the flow channel plate 50. The inlet 651 of the circulation pump 65 is connected to the clean water flow channel 51. The purified wash water can then flow through the clean water flow channel 51 to the circulation pump 65 for recycling.

[0187] In some embodiments, as Figure 7 and Figure 8As shown, the filter device 100 further includes a recoil member 55 disposed within the water purification chamber 12. The recoil member 55 includes a recoil flow channel 551 therein and a spray hole 552 disposed on the recoil member 55, which is connected to the recoil flow channel 551 and faces the water purification filter 30. Water ejected from the recoil member 55 through the spray hole 552 is sprayed onto the water purification filter 30, thereby removing debris stuck on the water purification filter 30, improving the filtration capacity of the water purification filter 30 and extending its service life.

[0188] Specifically, the clean water filter 30 is covered by the recoil member 55, which is disposed on the downstream side of the clean water filter 30, that is, on the side of the clean water filter 30 facing the clean water outlet 122. In this way, after the recoil member 55 sprays water onto the clean water filter 30, the residue stuck on the clean water filter 30 falls to the upstream side of the clean water filter 30, making it easier for the residue to be discharged from the waste outlet 123.

[0189] Alternatively, as Figure 8 As shown, the recoil member 55 is provided with a plurality of spray holes 552 arranged along the rotation axis of the water filter 30. The wash water sprayed from the plurality of spray holes 552 forms a spray line extending along the rotation axis of the water filter 30. The spray line of the plurality of spray holes 552 to the water filter 30 is long enough to fully spray away any debris stuck on the water filter 30.

[0190] In some embodiments, when the filter device 100 further includes: a circulation pump 65, the inlet end 651 of the circulation pump 65 is connected to the slag collection outlet 112 and the clean water outlet 122, and the outlet end 652 of the circulation pump 65 is connected to the backwash flow channel 551. The washing water filtered by the clean water filter 30 in the clean water chamber 12 can directly enter the circulation pump 65 through the inlet end 651 of the circulation pump 65, thereby increasing the flow rate of the washing water between the circulation pump 65 and the clean water chamber 12 and improving the circulation efficiency of the washing water. The backwash component 55 is housed in the clean water chamber 12 and is located on the upstream side of the clean water filter 30. The backwash component 55 is connected to the outlet end 652 of the circulation pump 65, and the washing water filtered in the clean water chamber 12 enters the inlet end 651 of the circulation pump 65. A spray hole 552 is formed on the recoil member 55, which is open toward the water purification filter 30. The washing water flowing into the recoil member 55 can be sprayed from the spray hole 552 onto the water purification filter 30 to remove the filter residue adhering to the surface of the water purification filter 30, reduce the possibility of clogging of the water purification filter 30, improve the cleanliness and water permeability of the water purification filter 30, reduce the loss of washing water, and improve the filtration efficiency and filtration effect of the water purification filter 30.

[0191] Specifically, if Figure 8As shown, the filter device 100 further includes a flow plate 50 disposed at the bottom of the structural body 10. A clean water flow channel 51 is provided within the flow plate 50, connecting the slag collection outlet 112 and the clean water outlet 122. A recoil member 55 is disposed at the top of the flow plate 50. A water supply flow channel 53 is provided within the flow plate 50, connecting the recoil flow channel 551. Using the flow plate 50 to connect the recoil member 55 provides high integration and facilitates assembly, while also reducing the number of parts and facilitating sealing.

[0192] Furthermore, the recoil element 55 is integrally formed on the top of the flow channel plate 50. A water supply channel 53 is provided within the flow channel plate 50, connecting to the recoil channel 551. In other words, the outlet 652 of the circulation pump 65 is connected to the water supply channel 53, and water then flows from the water supply channel 53 to the recoil channel 551. This eliminates the need for separate piping and simplifies the structure.

[0193] Specifically, if Figure 2 As shown, the wash water flowing out of outlet 652 of circulation pump 65 is split into two directions. Most of the wash water flows into the washing process, while a small portion flows into diverter pipe 56. The other end of diverter pipe 56 is connected to the structural body 10 and communicates with the water supply channel 53, thereby supplying the diverted wash water to the recoil element 55.

[0194] In some embodiments, as Figure 9 and Figure 11 As shown, a circulating water pipe 193 is provided at the bottom of the structural body 10. A spray arm flow channel 15 is provided within the structural body 10. The lower end of the spray arm flow channel 15 is connected to the circulating water pipe 193, and the upper end of the spray arm flow channel 15 forms a spray arm interface 151 at the top of the structural body 10. This arrangement facilitates the flow of filtered wash water, driven by the circulating pump 65, into the circulating water pipe 193, and then into the spray arm flow channel 15.

[0195] The spray arm interface 151 here is used to install the spray arm, and the spray arm can be a fixed arm or a rotating arm. By introducing washing water, the spray arm can spray washing water to items to be washed such as pots and pans, thereby improving cleanliness.

[0196] Specifically, at least two spray arm flow channels 15 are provided in the structural body 10. In order to ensure that each spray arm flow channel 15 can obtain a certain amount of washing water, the filtering device 100 also includes a water diversion valve 69, which is connected to the circulating water pipe 193 to evenly distribute the incoming water to different spray arm flow channels 15.

[0197] More specifically, one end of the diversion pipe 56 is connected to the circulating water pipe 193 and is located upstream of the water diversion valve 69 .

[0198] In some embodiments, as Figure 9 and Figure 10As shown, a water collecting chamber 14 is provided in the structural body 10, and the water collecting chamber 14 is used to collect the washing water of the cleaning device 1000, so that the washing water can be collected in the water collecting chamber 14 and discharged after the final washing is completed.

[0199] Specifically, the water collecting chamber 14 is connected to the slag collecting outlet 113, so that the residue collected in the slag collecting chamber 11 can be discharged from the water collecting chamber 14 together with the collected washing water. In this way, the impact of the washing water can be used to flush out the residue, reducing the phenomenon of residue sticking to the wall during the flushing process.

[0200] Furthermore, if Figure 9 and Figure 10 As shown, the water collecting chamber 14 is separated from the slag collecting chamber 11 by a one-way valve 61a, and the one-way valve 61a is opened in one direction from the slag collecting chamber 11 to the water collecting chamber 1. In this way, when the water collecting chamber 14 is not drained, the air pressure on one side of the water collecting chamber 14 can be slightly higher than that on the side of the slag collecting chamber 11, so that the one-way valve 61a closes the slag collecting outlet 113. In particular, when the cleaning equipment 1000 is in the washing state and the circulating pump 65 is turned on to put the slag collecting chamber 11 in a negative pressure state, the air pressure in the undrained water collecting chamber 14 is higher than that in the slag collecting chamber 11, thereby closing the slag collecting outlet 113. In this way, the washing water collected in the water collecting chamber 14 contains less residue, which is convenient for collection and reuse. The slag collecting chamber 11 is still in a continuous slag collecting and filtering state.

[0201] When the water collecting chamber 14 is drained, the air pressure on one side of the water collecting chamber 14 drops rapidly due to the rapid emptying. When the air pressure there is lower than the air pressure on the side of the slag collecting chamber 11, the one-way valve 61a can be opened to allow the collected residue to be discharged from the slag collecting outlet 113 to the water collecting chamber 14 and then discharged from the water collecting chamber 14.

[0202] In some embodiments, the water collection chamber 14 is separated from the slag collection chamber 11 by a one-way valve 61a. When the circulation pump 65 is shut down and the water collection chamber 14 is drained, the slag collection chamber 11 is positively pressurized, opening the one-way valve 61a. Turning on the circulation pump 65 indicates the start of the washing process, while shutting down the circulation pump 65 indicates the end of the washing process. Turning on and off the slag collection chamber 11 instantly adjusts the opening and closing state of the one-way valve 61a, providing very flexible slag discharge control without the need for a separate controller.

[0203] The lowest point of the water collecting chamber 14 is set to be lower than the slag collecting and discharging port 113 , so as to facilitate the emptying of the residue in the slag collecting chamber 11 and reduce the accumulation at the slag collecting and discharging port 113 .

[0204] In some embodiments, as Figure 10 As shown, the bottom wall surface S3 of the water collecting chamber 14 is lower than the bottom wall surface S1 of the slag collecting chamber 11, and a first step surface 141 is formed at the connection, and the one-way valve 61a is installed against the first step surface 141. This facilitates the emptying of the slag collecting chamber 11 while also facilitating the positioning and installation of the one-way valve 61a.

[0205] In some specific embodiments, Figure 11 As shown, the main body 10 is also provided with a drain port 175, which is connected to the slag collection and discharge port 113. A one-way valve 61a is provided at the slag collection and discharge port 113. The one-way valve 61a is configured to open in one direction from the slag collection chamber 11 to the drain port 175. In other words, during slag discharge, the residue is ultimately discharged from the drain port 175.

[0206] Specifically, if Figure 2 As shown, the water collection chamber 14 is connected to the sewage outlet 175, and the filter device 100 also includes a drain valve 67 for opening and closing the sewage outlet 175. When the circulation pump 65 is operating, the drain valve 67 is closed, and when the drain valve 67 is open, the circulation pump 65 is turned off. In this way, when the circulation pump 65 is operating, the slag collection chamber 11 is in a negative pressure state. At this time, the drain valve 67 is closed, and the water pressure in the water collection chamber 14 is high, thereby closing the one-way valve 61a. When the circulation pump 65 is turned off, the air pressure in the slag collection chamber 11 increases. At this time, the drain valve 67 opens, reducing the water pressure in the water collection chamber 14, allowing the residue to be automatically sucked into the water collection chamber 14 and eventually washed away by the water flow from the sewage outlet 175.

[0207] In some embodiments, as Figure 3 As shown, the main body 10 is further provided with a primary filter chamber 13 having a primary filter outlet 133 connected to the clean chamber inlet 121. The filter device 100 further includes a primary filter element 70 for filtering the wash water entering the primary filter chamber 13.

[0208] That is to say, the residue is filtered at least twice before entering the residue collecting chamber 11 along with the water flow, so that the residue is selected according to size, the load of the filter screen during each filtration is reduced, and the filtering effect is improved.

[0209] Specifically, if Figure 2 、 Figure 3 and Figure 9 As shown, the primary filter chamber 13 further includes: a primary filter vertical chamber 131, and a primary filter outlet 133 located on the outer peripheral wall of the primary filter vertical chamber 131. Figure 9 As shown, the primary filter element 70 includes a primary filter cup 71 with a first primary filter hole 701. The primary filter cup 71 is disposed within the primary filter chamber 13. The outer portion of the primary filter cup 71 forms a primary filter vertical chamber 131, and the inner portion of the primary filter cup 71 forms an unfiltered primary collection chamber 16. In other words, the primary filter cup 71 utilizes the entire cylindrical wall for filtration, resulting in a large filtration area and high filtration efficiency. At this point, the wash water that has undergone primary filtration enters the clean water chamber 12 through the primary filter outlet 133 on the outer periphery of the primary filter vertical chamber 131. The incoming water has a flow dynamic force, flushing the residue toward the waste outlet 123 and entering the residue collection chamber 11.

[0210] It should be noted that the maximum particle size passing through the primary filter cup 71 can be limited by the size of the first primary filter hole 701 on the primary filter cup 71. For example, when the width of the first primary filter hole 701 is set to 0.5 mm, the primary filter cup 71 can retain residue with a particle size exceeding 0.5 mm in the primary collection chamber 16, while residue with a particle size less than 0.1 mm may flow into the primary filter vertical chamber 131 with the wash water and enter the water purification chamber 12. Alternatively, at least one layer of filter cloth can be provided on the surface of the primary filter cup 71. The primary filter cup 71 is a rigid component used to support the filter cloth. The maximum particle size passing through the primary filter cup 71 is limited by the mesh size of the filter cloth.

[0211] Furthermore, if Figure 9 and Figure 10 As shown, the primary filter element 70 also includes: a primary filter bottom wall 73 with a second primary filter hole 702, the primary filter bottom wall 73 is connected to the bottom of the primary filter cup tube 71, the primary filter bottom wall 73 and the primary filter cup tube 71 form a filter cup, so that the large-sized residue filtered out can be concentrated in the filter cup, which is convenient for centralized cleaning.

[0212] It should be noted that the maximum passing particle size of the primary filter bottom wall 73 can be limited by the size of the second primary filter hole 702 on the primary filter bottom wall 73. For example, when the width of the second primary filter hole 702 is set at 3 mm, the primary filter bottom wall 73 can retain residues with a particle size exceeding 3 mm in the primary collection cavity 16. As for residues with a particle size less than 3 mm, a larger portion of the residues (residues smaller than the maximum passing particle size of the primary filter cup 71) may pass through the primary filter cup 71 and flow into the primary filter vertical cavity 131 along with the washing water, and enter the clean water cavity 12. Alternatively, at least one layer of filter cloth can be provided on the surface of the primary filter bottom wall 73. The primary filter bottom wall 73 is a rigid part used to support the filter cloth. The maximum passing particle size of the primary filter bottom wall 73 is limited by the mesh size of the filter cloth.

[0213] Furthermore, if Figure 1 and Figure 7 As shown, the primary filter element 70 further includes a primary filter plate 72 with a third primary filter hole 703. The primary filter plate 72 is located at the top of the structural body 10 and is provided with a relief opening 721. The primary filter plate 72 is sleeved onto the primary filter cup 71 through the relief opening 721. The primary filter chamber 13 further includes a primary filter horizontal cavity 132 located between the primary filter plate 72 and the top surface of the structural body 10. The primary filter horizontal cavity 132 is connected to the upper end of the primary filter vertical cavity 131.

[0214] In this way, the washing water can be filtered out from the primary filter plate 72 and enter the primary filter horizontal cavity 132, then enter the primary filter vertical cavity 131, and then enter the water purification cavity 12 for filtration. This arrangement makes the primary filtration process large in area, fast in filtration speed, and high in efficiency.

[0215] It should be noted that the maximum particle size passing through the primary filter plate 72 can be limited by the size of the third primary filter hole 703 on the primary filter plate 72. For example, when the width of the third primary filter hole 703 is set at 0.5 mm, the primary filter plate 72 can retain residue with a particle size exceeding 0.5 mm at the top, while residue with a particle size less than 0.5 mm may flow into the primary filter horizontal cavity 132 with the washing water and enter the water purification cavity 12. Alternatively, at least one layer of filter cloth can be provided on the surface of the primary filter plate 72. The primary filter plate 72 is a rigid member used to support the filter cloth. The maximum particle size passing through the primary filter plate 72 is limited by the mesh size of the filter cloth.

[0216] In some specific embodiments, Figure 7 As shown, the primary filter element 70 further includes a cup rim 74 connected to the upper edge of the primary filter cup 71, and the cup rim 74 is located above the primary filter plate 72. The cup rim 74 refers to the cup edge of the filter cup, and the arrangement of the cup rim 74 makes it easier for users to pick up the filter cup for cleaning.

[0217] The connection between the rim 74 and the primary filter cup 71 fits in the avoidance opening 721 of the primary filter plate 72. Optionally, the connection between the rim 74 and the primary filter cup 71 of the primary filter element 70 is consistent in shape and size with the avoidance opening 721, thereby achieving a relatively sealed connection without leaking residue.

[0218] Furthermore, a residue hole 704 is provided on the cup edge 74, which facilitates the water flow to carry the residue through the residue hole 704 and into the primary collection chamber 16. The residue hole 704 is set larger to facilitate the collection of all larger residues in the primary collection chamber 16 for centralized processing, thereby reducing the amount of residue remaining above the primary filter plate 72 and preventing the remaining residue from affecting the washing effect.

[0219] Specifically, the cup edge 74 is annular and is provided with a circle of slag holes 704 .

[0220] In some embodiments, as Figure 2 and Figure 3 As shown, the primary filter cup 71, the water purification filter 30 and the residue collection filter 20 are distributed in a triangular shape, so that the space required by the structural body 10 for the three can be centrally arranged. On the one hand, the external dimensions of the structural body 10 can be reduced, and on the other hand, the thickness of the partition wall between two adjacent cavities can be controlled, which is conducive to reducing weight.

[0221] Specifically, if Figure 9 As shown, when a water collection chamber 14 is provided within the structural body 10, the water collection chamber 14 is located below the primary collection chamber 16. This allows the water collection chamber 14 to collect wash water from the primary collection chamber 16. This shortens the water flow path and facilitates water collection after washing. Furthermore, it facilitates the processing and forming of the water collection chamber 14 and the primary collection chamber 16.

[0222] More specifically, the water collection chamber 14 is located below the primary collection chamber 16, separated from the primary collection chamber 16 by the primary filter bottom wall 73. As a result, debris with a particle size exceeding the maximum particle size passing through the primary filter bottom wall 73 remains in the primary collection chamber 16, that is, in the filter cup. However, debris with a particle size smaller than the maximum particle size passing through the primary filter bottom wall 73 can fall into the water collection chamber 14. This allows some debris to accumulate in the water collection chamber 14 during the washing process and be discharged with the water when the washing is complete.

[0223] Optionally, the water collection chamber 14 is located below both the primary collection chamber 16 and the primary filter vertical chamber 131. When the filter device 100 is in operation, the water flow will be driven by the circulation pump 65, and after primary filtration, it will enter the primary filter vertical chamber 131 from the cleaning space 201. The filtered washing water enters the clean water chamber 12 with small-particle residues, and most of the washing water is filtered again and returns to the circulation pump 65. A small part of the washing water enters the residue collection chamber 11 with a large amount of filtered small-particle residues. The washing water is filtered again in the residue collection chamber 11, and the filtered washing water returns to the circulation pump 65, and the remaining residue remains in the residue collection chamber 11. During the filtration process, some residue in the primary collection chamber 16 will sink into the water collection chamber 14 with the water flow. As more and more residue sinks into the water collection chamber 14, the washing water accumulated in the water collection chamber 14 is squeezed back into the primary filter chamber 13 and participates in the circulating flow of the washing water. After the filter device 100 is used, the washing water can flow to the water collection chamber 14 and be discharged from the water collection chamber 14, while the water is drained away. The residue in the water collection chamber 14 and the residue collection chamber 11 is taken away. The larger residue remains in the filter cup and is manually removed from the filter cup.

[0224] In the present application, the main chamber structure of the filter device 100 is formed on the structural body 10. That is to say, the structural body 10 is the main structure supporting the function of the filter device 100. For a clearer understanding of the function of the filter device 100, the following reference is made to Figure 11 The structure of the structural main body 10 of the embodiment of the present utility model is described in detail with reference to the accompanying drawings.

[0225] According to the structural body 10 of the embodiment of the present invention, a horizontally arranged primary filter chamber 131, a water purification chamber 12, and a residue collection chamber 11 are provided within the structural body 10. As described above, the primary filter chamber 131 can be equipped with a primary filter cup 71 for primary filtration. The water purification chamber 12 can be equipped with a water purification filter 30 for secondary filtration, and the residue collection chamber 11 is used to collect residue remaining after filtration. The structural body 10 is also provided with a water collection chamber 14 for collecting wash water flowing into the other chambers, thereby facilitating centralized drainage.

[0226] The side wall S7 of the primary filter vertical cavity 131 is provided with a primary filter outlet 133. The clean water cavity 12 has a clean cavity inlet 121, a clean water outlet 122 and a waste outlet 123. The clean cavity inlet 121 is connected to the primary filter outlet 133. Figure 11and Figure 9 The slag collecting chamber 11 has a slag collecting inlet 111 and a slag collecting outlet 113. The slag collecting inlet 111 is connected to the waste outlet 123, and the slag collecting outlet 113 is connected to the water collecting chamber 14 to discharge slag when the water collecting chamber 14 is drained. The separated clean washing water can be discharged from at least the clean water outlet 122 for recycling.

[0227] Arranging the primary filtration vertical cavity 131 , the water purification cavity 12 and the slag collecting cavity 11 horizontally can reduce the overall occupied height and help control the height dimension of the structural body 10 .

[0228] Specifically, if Figure 6 As shown, the bottom wall surface S1 of the slag collecting chamber 11 includes a diversion bottom surface S11, which gradually decreases in height toward the slag collecting and discharging port 113. The lowest point of the water collecting chamber 14 is lower than the slag collecting and discharging port 113. This allows for smooth discharge of residue from the slag collecting chamber 11 to the water collecting chamber 14, thereby increasing the probability of emptying the slag collecting chamber 11.

[0229] In some embodiments, as Figure 2 and Figure 11 As shown, a portion of the structural body 10 is formed by a converging wall column 180, around which the primary filtration vertical chamber 131, the clean water chamber 12, and the residue collection chamber 11 are arranged. These three chambers form a roughly triangular arrangement, creating a compact footprint and contributing to the reduction in the overall dimensions of the structural body 10. This arrangement allows the residue to circulate with the water within a relatively small space, resulting in a long flow path and sufficient separation and discharge of the wash water.

[0230] In some embodiments, the portion of the structural body 10 between the primary filter vertical cavity 131 and the water purification cavity 12 is the first wall plate 181. Figure 2 and Figure 11 As shown, one end of the first wall plate 181 is connected to the intersection wall column 180 , and the primary filter outlet 133 and the clean cavity inlet 121 are provided on the first wall plate 181 .

[0231] The portion of the structural body 10 separating the clean water chamber 12 and the slag collection chamber 11 is a second wall panel 182, one end of which is connected to the intersection wall column 180. The waste outlet 123 and the slag collection inlet 111 are located on the second wall panel 182. This allows the water to flow smoothly from the primary filter vertical chamber 131 to the clean water chamber 12 and the slag collection chamber 11 in sequence, carrying unfiltered residue. This reduces turbulence generated when the water flows from one chamber to the other, thereby reducing water flow resistance and lowering energy consumption.

[0232] In some embodiments, as Figure 2 and Figure 11As shown, the waste outlet 123 and the slag collection inlet 111 are provided at an end of the second wall plate 182 away from the intersection wall column 180 .

[0233] The waste outlet 123 is located at the end of the second wall panel 182 away from the intersection wall column 180, and is circumferentially farther from the clean cavity inlet 121. This reduces the probability of filtered residue backflowing from the clean cavity inlet 121. Furthermore, the slag discharge channel 184 between the waste outlet 123 and the slag collection inlet 111 can be shortened for easier processing. The shorter slag discharge channel 184 makes it less likely for residue to clog the channel 184.

[0234] In some embodiments, as Figure 11 As shown, the first wall plate 181 is provided with an exhaust hole 124 connecting the primary filter vertical chamber 131 and the water purification chamber 12. This can balance the air pressure inside and outside the water purification chamber 12, allowing the washing water filtered by the primary filter vertical chamber 131 to enter the water purification chamber 12 smoothly.

[0235] Specifically, if Figure 11 As shown, the vent 124 is higher than the primary filter outlet 133, so that the water in the primary filter vertical chamber 131 flows from the primary filter outlet 133 to the water purification chamber 12, and the water flow height is generally within the height range of the primary filter outlet 133. The vent 124 is higher than the primary filter outlet 133, which can prevent water from flowing into the vent 124 and causing water sealing.

[0236] Specifically, if Figure 11 As shown, the vent 124 is located on the side of the primary filter outlet 133 near the intersection wall 180. It is understood that, as designed, the water flow within the clean water chamber 12 is circumferential, flowing from the clean chamber inlet 121 toward the waste outlet 123. During this flow, a large amount of wash water flows radially toward the central clean water outlet 122. The vent 124 is located on the side of the primary filter outlet 133 near the intersection wall 180. In the direction of water flow within the clean water chamber 12, the vent 124 is located downstream of the clean chamber inlet 121 and the waste outlet 123. This reduces the probability of water and debris rushing toward the vent 124, thereby reducing the probability of clogging the vent 124.

[0237] In some embodiments, the slag collection inlet 111 is located on the side wall S2 of the slag collection chamber 11 and is higher than the slag collection water outlet 112 and the slag collection outlet 113. This can prevent water and residue in the slag collection chamber 11 from flowing back through the slag collection inlet 111.

[0238] In some embodiments, the sidewall surface of the slag collection chamber 11 opposite the slag collection inlet 111 is a first curved surface S3-1. The two ends of the first curved surface S3-1 correspond to the slag collection inlet 111 and the slag collection outlet 113. The center of the first curved surface S3-1 is configured to protrude away from the slag collection outlet 112, relative to the two ends. Thus, when a high-speed water flow drives debris into the slag collection chamber 11 from the slag collection inlet 111, the debris is ejected onto the first curved surface S3-1, thereby converging along the first curved surface S3-1 toward the slag collection outlet 113. This facilitates improving the efficiency of debris collection by utilizing the first curved surface S3-1.

[0239] Specifically, the area of ​​the slag collection inlet 111 is larger than the flow area of ​​the slag collection outlet 113. It is understandable that the slag collection inlet 111 is always open during the washing process. The larger area of ​​the slag collection inlet 111 can improve the convenience of residue entry, while the smaller slag collection outlet 113 is convenient to close, making it easier to adjust the slag collection chamber 11 to a negative pressure state.

[0240] In some embodiments, the horizontal projection of the slag collecting chamber 11 is an elongated strip. The sidewall surface S2 of the slag collecting chamber 11 includes a first sidewall surface S21, a second sidewall surface S22, a third sidewall surface S23, and a fourth sidewall surface S24, which are sequentially connected. The first sidewall surface S21 and the third sidewall surface S23 are disposed opposite each other, and the second sidewall surface S22 and the fourth sidewall surface S24 are disposed opposite each other.

[0241] The primary filter vertical cavity 131 and the water purification cavity 12 are located on the side of the first side wall S21 away from the third side wall S23. The length of the first side wall S21 is greater than the length of the second side wall S22 and the fourth side wall S24, and the length of the third side wall S23 is greater than the length of the second side wall S22 and the fourth side wall S24.

[0242] Such arrangement makes the overall space occupied by the three cavities close to a rectangle, which facilitates the processing of the structural body 10.

[0243] In some embodiments, the water purification filter 30 is rotatably disposed within the water purification chamber 12, and the rotation direction of the water purification filter 30 is arranged tangentially at the waste outlet 123 toward the slag collection inlet 111. In this way, when the residue thrown off the water purification filter 30 slides along the side wall S5 of the water purification chamber 12 and encounters the waste outlet 123, it can slide along the waste outlet 123 toward the slag collection inlet 111 and enter the slag collection chamber 11. This helps the residue enter the slag collection chamber 11 smoothly and reduces the accumulation of residue in the water purification chamber 12.

[0244] In some embodiments, as Figure 3As shown, the slag collection inlet 111 is provided on the first side wall surface S21, and the edge of the slag collection inlet 111 is located on the second side wall surface S22. In other words, when water flows into the slag, it can smoothly slide onto the second side wall surface S22, increasing the sliding speed of the slag along the wall and helping the slag to continue to gather towards the slag collection outlet 113.

[0245] In some embodiments, as Figure 2 and Figure 11 As shown, the water purification chamber 12 is a cylindrical chamber, and the line connecting the center of the water purification chamber 12 and the waste outlet 123 is the slag discharge diameter line L1.

[0246] The second side wall surface S22 extends in a direction perpendicular to the slag discharge line L1 , and the slag discharge channel 184 between the waste outlet 123 and the slag collection inlet 111 extends in a direction perpendicular to the slag discharge line L1 .

[0247] Here, the water purification chamber 12 is a cylindrical chamber, which helps the water flow carrying the residue along the side wall S5 of the water purification chamber 12 to obtain a stable centrifugal force, thereby helping the residue to be thrown out from the waste outlet 123 after encountering the waste outlet 123.

[0248] The slag discharge channel 184 between the waste outlet 123 and the slag collection inlet 111 is extended in a direction perpendicular to the slag discharge diameter line L1. The slag discharge channel 184 is arranged nearly tangentially along the water purification chamber 12, which is consistent with the inertial force exerted by the residue at the waste outlet 123, so that the residue can be quickly discharged into the slag collection chamber 11 along the slag discharge channel 184. This arrangement allows the residue to enter the slag collection chamber 11 at a relatively high speed, allowing the residue to be concentrated toward the slag collection outlet 113 under the action of the inertial force, thereby improving the slag collection efficiency.

[0249] In some specific embodiments, Figure 3 As shown, the third side wall surface S23 is a first arcuate surface S3-1, and the middle and opposite ends of the first arcuate surface S3-1 are protruded in a direction away from the intersection wall column 180. Figure 2 As shown, when the water flow is fast and drives the residue from the residue collection inlet 111 into the residue collection chamber 11, the residue is sprayed onto the first curved surface S3-1, and then concentrated along the first curved surface S3-1 toward the residue collection outlet 113. This is conducive to improving the collection efficiency of the residue with the help of the first curved surface S3-1.

[0250] In some specific embodiments, Figure 3 As shown, the first side wall surface S21 is the second arc surface S1-1. Figure 2 As shown, the second arc-shaped surface S1 - 1 forms a convex corner 185 protruding toward the intersecting wall column 180 at the intersecting wall column 180 , thereby expanding the capacity of the slag collecting chamber 11 .

[0251] Specifically, the slag collecting chamber 11 further includes a slag collecting outlet 112 disposed on the bottom wall surface S1 of the slag collecting chamber 11. This outlet 112 is located adjacent to the convex corner 185. Water flowing into the convex corner 185 slows down and easily flows out of the slag collecting outlet 112. Furthermore, when the slag collecting outlet 112 is provided here, a slag collecting filter 20 can also be installed there. The convex corner 185 provides space for the slag collecting filter 20 to move, thereby increasing the filtration area of ​​the slag collecting filter 20 and improving the filtration effect.

[0252] In some specific embodiments, Figure 6 and Figure 8 As shown, the structural body 10 includes a platform 114 provided on the bottom wall surface S1 of the slag collecting chamber 11. The platform 114 is arranged around the slag collecting outlet 112. The slag collecting filter 20 can be made higher than the bottom wall surface S1 of the slag collecting chamber 11, thereby reducing the amount of bottom residue flowing from the gap below the slag collecting filter 20 to the slag collecting outlet 112.

[0253] In some specific embodiments, the waste outlet 123 is higher than the bottom wall surface S6 of the water purification chamber 12 , so as to prevent the residue in the slag collecting chamber 11 from being directly impacted by the water flow and returning to the water purification chamber 12 .

[0254] In some specific embodiments, Figure 11 As shown, the top of the structural body 10 is provided with a slag collection cleaning port 171 connected to the slag collection chamber 11 and a clean cavity cleaning port 172 connected to the clean water chamber 12. This facilitates observation, cleaning, and maintenance operations from the slag collection cleaning port 171 and the clean cavity cleaning port 172 during inspection or cleaning.

[0255] In some specific embodiments, the top of the primary filter vertical cavity 131 is open to facilitate the assembly of the filter cup.

[0256] The top edge of the structural body 10 forms a mating flange 192, which encloses a primary filter horizontal cavity 132 with the top surface of the structural body 10. The primary filter horizontal cavity 132 communicates with the upper end of the primary filter vertical cavity 131. This facilitates the installation of the primary filter plate 72 using the mating flange 192, ultimately positioning the primary filter plate 72 at the top of the structural body 10. This allows wash water to quickly filter through the primary filter plate 72 from above and enter the primary filter horizontal cavity 132.

[0257] In some specific embodiments, Figure 9 and Figure 10As shown, the water collection chamber 14 is located below and connected to the primary filter vertical chamber 131. The portion of the structural body 10 separating the water collection chamber 14 and the slag collection chamber 11 is a third wall plate 183, and the slag collection outlet 113 is located on this third wall plate 183. This shortens the distance between the water collection chamber 14 and the slag collection chamber 11, making the third wall plate 183 thinner. This not only facilitates weight reduction, but also shortens the slag discharge path, facilitating the emptying of residue from the slag collection chamber 11.

[0258] In some specific embodiments, Figure 10 As shown, the bottom wall S3 of the water collecting chamber 14 is lower than the bottom wall S1 of the slag collecting chamber 11, and a first step surface 141 is formed at the connection. This not only facilitates the emptying of the residue in the slag collecting chamber 11, but also facilitates the use of the first step surface 141 to position the slag discharge valve 61, improving the assembly convenience of the slag discharge valve 61.

[0259] Specifically, an internal connection portion 142 is formed at the connection between the side wall surface S4 of the water collecting chamber 14 and the side wall surface S7 of the primary filter vertical chamber 131, which makes it convenient to place the primary filter cup cartridge 71 on the internal connection portion 142. The internal connection portion 142 becomes the installation positioning portion of the primary filter cup cartridge 71, facilitating the installation of the filter cup.

[0260] Specifically, the internal connection portion 142 is extended along the radial direction of the primary filter vertical cavity 131 , which has a simple structure and is easy to assemble smoothly.

[0261] Furthermore, the internal connection portion 142 is in a circular ring shape and is provided with a bayonet. The primary filter element 70 includes a buckle provided on the outer peripheral surface of the primary filter cup 71 , and the buckle is clamped in the bayonet.

[0262] In some specific embodiments, Figure 11 As shown, a drain pipe 191 is provided on the outer side of the structural body 10. One end of the drain pipe 191 is connected to the water collection chamber 14, and the other end of the drain pipe 191 is open to install the drain valve 67. A sewage outlet 175 is provided on the wall of the drain pipe 191. This arrangement facilitates the installation of the drain valve 67.

[0263] In some specific embodiments, Figure 9 As shown, a water inlet 194 is provided on the structural body 10 , and the water inlet 194 is provided on the peripheral wall of the primary filter vertical cavity 131 to facilitate the introduction of water flow.

[0264] like Figure 12 As shown, a cleaning device 1000 according to an embodiment of the present invention includes the structural body 10 described in the above embodiment. The cleaning device 1000 according to an embodiment of the present invention also includes the filtering device 100 described in the above embodiment. The structures of the structural body 10 and filtering device 100 are not described in detail here. The cleaning device 1000 also includes an apparatus body 200. The structural body 10 is integrated with the apparatus body 200, and the apparatus body 200 defines a cleaning space V1.

[0265] Specifically, a slag collecting chamber 11 is provided within the structural body 10. The slag collecting chamber 11 is located below the cleaning space V1, and the bottom of the cleaning space V1 is connected to the slag collecting inlet 111. Alternatively, a slag collecting chamber 11 and a clean water chamber 12 are formed within the structural body 10. The slag collecting chamber 11 and the clean water chamber 12 are located below the cleaning space V1, and the bottom of the cleaning space V1 is connected to the clean chamber inlet 121. Alternatively, a primary filtration vertical chamber 131, a slag collecting chamber 11, and a clean water chamber 12 are formed within the structural body 10. The slag collecting chamber 11 and the clean water chamber 12 are located below the cleaning space V1, and the bottom of the cleaning space V1 is connected to the clean chamber inlet 121.

[0266] The cleaning device 1000 of the present invention can improve the filtration effect of washing water by using the filter device 100, thereby providing cleaner washing water for recycling and improving the cleaning degree. In addition, the service life of each filter screen in the filter device 100 is long, and the filtration effect can be maintained for a long time.
