Description

Technical Field

[0001] This invention relates to the field of washing equipment, and more specifically to a filtration device and a washing equipment. Background Technology

[0002] Cleaning equipment typically includes a filtration system to filter the water flow, allowing for the reuse of the wash water. In conventional cleaning equipment, the residue filtered out remains on the filter screen, which is then manually removed after the items are washed to clean the residue. This design increases the workload of removing residue and is relatively cumbersome to use. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a filtration device that can automatically collect residues in washing water, improving the ease of use of the filtration device.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0066] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] The following is a reference appendix. Figures 1-11 The present invention describes a filtration device 100 for a cleaning apparatus 1000 according to an embodiment of the present invention. The filtration device 100 is used to filter the washing water of the cleaning apparatus 1000 to remove residues from the washing water and improve the cleanliness of the washing water. The filtered washing water can be used for recycling or in other applications, such as irrigation, thereby improving the utilization rate of the washing water.

[0068] The filter device 100 of the cleaning apparatus 1000 according to an embodiment of the present invention, with reference to Figure 1It includes: main structure 10, which is the main structure of filter device 100, and undertakes the functions of support and protection, providing a closed filtration environment for washing water.

[0069] Reference Figure 2 and Figure 3 The main structural body 10 is equipped with a slag collection chamber 11. For example... Figure 6 As shown, the slag collection chamber 11 has a slag inlet 111 and a slag outlet 113. The water flow carries the residue into the slag collection chamber 11 from the slag 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 collection chamber 11. Then, at an appropriate time, the residue can be discharged from the slag outlet 113.

[0070] This application does not limit the method of separating washing water and residue in the slag collection chamber 11. For example, after the water flow carries the residue into the slag collection chamber 11, after a certain period of sedimentation, the residue and water automatically separate into layers under the action of gravity. The residue remains at the bottom layer, and the washing water remains at the top layer. At this time, the washing water at the top layer is extracted, and the residue stored in the slag collection chamber 11 is the residue with reduced water content. Another example is... Figure 6 As shown, a slag collection filter screen 20 is installed in the slag collection chamber 11 along the flow path from the slag collection inlet 111 to the slag collection outlet 113. During the flow, the washing water is gradually filtered out by the slag collection filter screen 20, and the remaining residue with reduced water content remains in the slag collection chamber 11.

[0071] In some embodiments, such as Figure 2 As shown, the slag collection chamber 11 has a slag collection outlet 112, such as... Figure 4 As shown, the filtration device 100 also includes a slag collection filter screen 20. The slag collection filter screen 20 is located inside the slag collection chamber 11 and at the slag collection outlet 112. The slag collection filter screen 20 filters the water flowing towards the slag collection outlet 112, leaving the residue in the slag collection chamber 11. After filtration by the slag collection filter screen 20, clean washing water can be discharged from the slag collection outlet 112. This discharged washing water can be recycled or directly discharged. Filtering the washing water from the residue out of the slag collection chamber 11 allows it to hold only the residue, reducing the volume required for residue storage and allowing more residue to accumulate in the chamber. Furthermore, the residue is almost solid, making it easier to concentrate in the slag collection chamber 11 for subsequent processing. For example, when manual slag removal is required, it is relatively easy to collect and remove the residue. Moreover, if the filtered washing water in the slag collection chamber 11 can be recycled, the washing water utilization rate can be improved, reducing the water consumption of the cleaning equipment 1000.

[0072] In some embodiments, such as Figure 6As shown, the filter device 100 also includes a slag discharge valve 61, which is located at the slag collection outlet 113. By closing the slag collection outlet 113 with the slag discharge valve 61, the slag collection outlet 113 can be positioned lower within the slag collection chamber 11, or even at the lowest point of the slag collection chamber 11, such as at the lowest point of the bottom wall S1 or the lowest point of the side wall S2. This facilitates the emptying of residue from the slag collection chamber 11 during slag discharge. Furthermore, the slag discharge valve 61 can close the slag collection outlet 113 when slag discharge is not required, allowing the residue to settle and undergo sufficient liquid-solid separation after entering the slag collection chamber 11, thus filtering out more washing water.

[0073] In this application, the structure of the slag discharge valve 61 is not limited; it can be an electromagnetic switch valve or other types of valves.

[0074] In some specific embodiments, such as Figure 6 As shown, the slag discharge valve 61 is a one-way valve 61a that opens only outward from the slag collection chamber 11. The one-way valve 61a is controlled to open and close by the pressure difference between 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. Moreover, the one-way valve 61a itself usually has a simple structure, is easy to assemble, and can also reduce its volume, which is conducive to the compact layout of the filter device 100.

[0075] Specifically, such as Figure 8 As shown, when a one-way valve 61a is installed at the slag collection outlet 113, a slag collection water outlet 112 is also installed in the slag collection chamber 11, as well as a slag collection filter screen 20 installed at the slag collection water outlet 112. This can reduce the pressure exerted by the washing water on the one-way valve 61a and prevent the one-way valve 61a from being accidentally opened due to improper closure.

[0076] In some specific embodiments, such as Figure 9 and Figure 10 As shown, the one-way valve 61a includes a bracket 611 and a valve cover 612. The bracket 611 has a through valve port 6113 and is installed at the slag collection outlet 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 air pressure applied to 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 outlet 113, the valve cover 612 is sucked into the valve port 6113 and kept closed. When the air pressure inside the slag collection chamber 11 is higher than the air pressure outside the slag collection outlet 113, the valve cover 612 is pushed open to open the valve port 6113. The exterior of the slag collection outlet 113 here refers to the side away from the slag collection chamber 11 on both sides of the one-way valve 61a. Figure 10The air pressure in the central water chamber 14 is the same as the external air pressure at the slag collection and discharge port 113.

[0077] This one-way valve 61a is thin and does not take up too much space. It is easy to open and close and is not easily blocked, which may prevent it from closing or opening.

[0078] Specifically, the valve cover 612 is a flexible cover. In its natural state, the valve cover 612 fits at the valve port 6113, that is, when there is no pressure difference between the inside of the slag collection chamber 11 and the outside of the slag collection outlet 113, the valve cover 612 fits at the valve port 6113. In this way, when the air pressure inside the slag collection chamber 11 is lower than the air pressure outside the slag collection outlet 113, the valve cover 612 can quickly find the valve port 6113 and close the valve port 6113.

[0079] Specifically, such as Figure 10 As shown, the upper end of the valve cover 612 is connected to the bracket 611, which facilitates the valve cover 612 to droop under gravity in its natural state to fit at the valve port 6113.

[0080] Specifically, when the support 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 collection and discharge port 113.

[0081] In some specific embodiments, such as Figure 10 As shown, the bracket 611 has a socket 6114, and the valve cover 612 has a post 6125, which is fitted into the socket 6114. Alternatively, the bracket 611 has a post 6125, and the valve cover 612 has a socket 6114, with the post 6125 fitted into the socket 6114. This design facilitates assembly and disassembly for cleaning.

[0082] 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 above the valve port 6113. This is beneficial for the valve cover 612 to fit into the valve port 6113 when it hangs down under gravity in its natural state.

[0083] Furthermore, such as Figure 10 As shown, the valve cover 612 is provided with a plug 6125, and the end of the plug 6125 is an expansion block 6127 to achieve a limit.

[0084] In some embodiments, such as Figure 10As shown, the valve cover 612 is provided with a groove 6126, which is located between the insert post 6125 and the valve port 6113. The groove 6126 is a weak stress point on the valve cover 612. When the air pressure inside the slag collection chamber 11 is relatively higher than the air pressure outside the slag collection outlet 113, and the valve cover 612 needs to be pushed open to open the valve port 6113, the valve cover 612 can be bent at the groove 6126, making it easier to open the valve port 6113. Optionally, the groove 6126 is a transverse through groove.

[0085] Specifically, such as Figure 10 As shown, the bracket 611 has a positioning rib 6117 on the side facing the valve cover 612, and the positioning rib 6117 is located in the wire groove 6126. In this way, the air pressure inside the slag collection chamber 11 is lower than the air pressure outside the slag collection outlet 113. When the valve cover 612 is sucked in, the valve cover 612 can be quickly and accurately closed at the valve outlet 6113 by the action of the positioning rib 6117 inserting into the wire groove 6126.

[0086] Specifically, the valve cover 612 is made of soft rubber, which not only allows the valve cover 612 to be opened and closed repeatedly, but also makes it less prone to breakage after repeated bending, resulting in a long service life.

[0087] Optionally, the valve cover 612 and the insert 6125 are integrally molded parts, thereby facilitating processing and reducing the risk of breakage. Further optionally, the valve cover 612 is a soft rubber sheet, and the valve cover 6122, insert 6125, and expansion block 6127 are all integrally molded parts. The insert 6215 is a hollow tube with an opening at the end facing the expansion block 6127, facilitating extrusion deformation for assembly.

[0088] In some embodiments, such as Figure 10 As shown, the one-way valve 61a also includes a reinforcing cover plate 613, which is mounted on a soft rubber sheet and positioned directly opposite the valve port 6113. This increases the strength of the valve cover 612 at the valve port 6113, preventing the valve cover 612 from being excessively sucked in and deformed when the air pressure inside the slag collection chamber 11 is too low compared to the air pressure outside the slag collection outlet 113, thus avoiding excessive deformation that could prevent the valve port 6113 from closing.

[0089] Specifically, such as Figure 10 As shown, the valve cover 612 is provided with a cover groove 6122, and the reinforcing cover plate 613 is fitted into the cover groove 6122. Furthermore, the reinforcing cover plate 613 is interference-fitted into the cover groove 6122, thereby securing the reinforcing cover plate 613.

[0090] Specifically, an open groove 6122 is formed on the side of the valve cover 612 away from the slag collection chamber 11 for easy assembly. Furthermore, this side does not directly encounter water flow or residue, reducing the risk of the reinforcing cover plate 613 detaching from the valve cover 612. The opening area of ​​the groove 6122 is smaller than the corresponding area of ​​the reinforcing cover plate 613, allowing the valve cover 612 to easily cover the reinforcing cover plate 613 to prevent it from falling off.

[0091] Optionally, such as Figure 10 As shown, the valve cover 612 has a positioning protrusion 6121 on the side facing the slag collection chamber 11. The positioning protrusion 6121 is used to insert into the valve port 6113 when the valve cover 612 is closed, thereby improving the firmness and sealing when closed.

[0092] Alternatively, the positioning protrusion 6121 and the valve port 6113 may have the same shape. For example, both the positioning protrusion 6121 and the valve port 6113 may be semi-circular.

[0093] In some specific embodiments, such as Figure 10 As shown, the filter device 100 also includes a first sealing ring 614, which is sleeved on the bracket 611 to achieve a sealing connection between the edge of the bracket 611 and the inner wall of the slag collection and discharge port 113. The first sealing ring 614 also helps the bracket 611 to be clamped at the slag collection and discharge port 113, making it less likely to be knocked down by the pressure difference force or the impact force of the residue during slag discharge.

[0094] In some embodiments, such as Figure 6 As shown, the bottom wall surface S1 of the slag collection chamber 11 includes a guide bottom surface S11, the height of which gradually decreases from the slag collection inlet 111 to the slag collection outlet 113. In this way, the residue entering the slag collection chamber 11 from the slag collection inlet 111 can be guided by the guide bottom surface S11 to concentrate at the slag collection outlet 113, increasing the concentration of residue and facilitating the centralized separation of washing water and discharge of residue.

[0095] Specifically, the inclination angle α of the guide 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 guide bottom surface S11 to at least 5° allows the gravity and water flow impact force on the residue to overcome the adhesion to the guide bottom surface S11. This allows the residue to slide quickly at the bottom of the slag collection chamber 11, reducing the amount of residue adhering to the walls of the guide bottom surface S11.

[0096] In some embodiments, the bottom wall surface S1 of the slag collection chamber 11 further includes a recessed surface S12, one end of which is connected to the lowest edge of the guide bottom surface S11. The height of the recessed surface S12 gradually decreases in the direction towards the guide bottom surface S11. This configuration creates a downward depression at the junction of the recessed surface S12 and the guide bottom surface S11, allowing the residue to concentrate within the depression, which provides a certain capacity. Forming a depression here, rather than one attached to the side wall surface S2 of the slag collection chamber 11, can effectively prevent residue from accumulating at the corners, thus facilitating the emptying of the residue.

[0097] Specifically, the slag discharge port 113 is located on the side wall surface S2 of the slag collection chamber 11, and is set at the connection between the sinking concave surface S12 and the guide bottom surface S11. This helps to concentrate the residue concentrated on the sinking concave surface S12 and discharge it from the slag discharge port 113, reducing the amount of residue retained in the slag collection chamber 11.

[0098] Specifically, at least part of the lower edge of the slag collection outlet 113 coincides with the intersection line of the sinking concave surface S12 and the side wall surface S2 of the slag collection cavity 11. This not only facilitates the processing of the slag collection outlet 113, but also allows the residue to be smoothly discharged along the slag collection outlet 113, avoiding the situation where there are steps at the slag collection outlet 113 that cause residue to stagnate.

[0099] More specifically, the intersection of the concave surface S12 and the side wall S2 of the slag collection cavity 11 includes a concave line S1-2, which coincides with the lower edge of the slag discharge port 113. The lowest point in the middle of the concave line S1-2 is also the lowest point inside the slag collection cavity 11, which helps to smoothly discharge the residue.

[0100] Specifically, the bottom surface of the guide is an inclined surface, the highest side of the bottom surface of the guide is set to the slag collection inlet 111, and the lowest side of the bottom surface of the guide is set to the slag collection outlet 113.

[0101] Specifically, the concave surface S12 is an arc-shaped surface. Optionally, the concave line S1-2 in the intersection of the concave surface S12 and the side wall surface S2 of the slag collection cavity 11 is a circular arc. Further optionally, the central angle of the concave line S1-2 is at least 90 degrees.

[0102] The lateral distance from the highest edge to the lowest edge of the concave surface S12 is much smaller than the lateral distance from the highest edge to the lowest edge of the guide bottom surface S11.

[0103] In some specific embodiments, the height difference of the guide bottom surface S11 is at least 5% of the height of the slag collection chamber 11.

[0104] Understandably, the slag collection chamber 11 is designed to be relatively large, partly to hold the washing water when the water flow is high, providing sufficient space for the separation of washing water and residue. Setting the height difference between the lowest point of the concave surface S12 and the lowest edge of the guide bottom surface S11 to at least 5% of the height of the slag collection chamber 11 provides sufficient concentrated space for residue storage and creates a shape that is wider at the top and narrower at the bottom, resulting in a faster flow velocity in the upper area where there is more residue and a smaller amount of residue in the lower area where the flow velocity is lower. This facilitates the emptying of residue.

[0105] Optionally, the height difference of the guide bottom surface S11 can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, etc., of the height of the slag collection chamber 11. Typically, the height difference of the guide bottom surface S11 will not exceed 20% of the height of the slag collection chamber 11. This avoids making the slag collection chamber 11 too high, which would result in the overall filter device 100 being too high.

[0106] In some embodiments, such as Figure 2 and Figure 4 As shown, the filter device 100 also includes a sludge-collecting and agitating element 22, which is disposed in the sludge-collecting chamber 11 and is adapted to agitate the filter sludge. This arrangement promotes water flow, helps prevent residue from settling and adhering to the wall, and facilitates the collection and discharge of residue towards the sludge outlet 113.

[0107] In particular, once the residue settles to the bottom, it easily pushes the water upwards, causing the bottom residue to become dry, hard, and sticky to the bottom wall surface S1. The slag collection and turbulence device 22 allows the bottom residue to mix with the washing water above, so that the washing water can carry away the residue as it flows, thus helping the residue to concentrate towards the slag collection outlet 113.

[0108] Here, the structure of the slag collection and flow disturbance component 22 is not limited. The slag collection and flow disturbance component 22 can be a fixed component inside the slag collection cavity 11, or it can be a movable component inside the slag collection cavity 11.

[0109] In some specific embodiments, the sludge collecting and agitating component 22 is a movable component, and the sludge collecting and agitating component 22 is configured to move under the influence of water flow. That is, the impact of water flow drives the sludge collecting and agitating component 22 to move, and the movable sludge collecting and agitating component 22 can agitate the filter cake. The agitation action of the sludge collecting and agitating component 22 is achieved by utilizing the kinetic energy of the water flow, without the need for a separate drive component, which not only saves the number of parts but also improves energy efficiency.

[0110] In other specific embodiments, such as Figure 5 and Figure 6As shown, the filtration device 100 also includes a drive assembly 40, which is connected to the sludge-collecting agitator 22 to drive the sludge-collecting agitator 22 to move. In other words, the movement of the sludge-collecting agitator 22 is driven by the drive assembly 40, which not only provides high controllability but also allows the sludge-collecting agitator 22 to move even when the water flow energy is insufficient. This helps maintain continuous agitation of the filter cake and further reduces the phenomenon of filter cake settling and adhering to the wall.

[0111] In some specific embodiments, the slag collection and turbulence-disrupting component 22 is rotatably disposed in the slag collection cavity 11, and the driving component 40 is used to drive the slag collection and turbulence-disrupting component 22 to rotate. In this way, the structure of the driving component 40 is relatively simple, and there is no need to set up an overly complex transmission structure, thereby reducing the space occupied.

[0112] In some specific embodiments, such as Figure 2 As shown, the slag collection chamber 11 also has a slag collection outlet 112, and the filtration device 100 also includes a slag collection filter screen 20 disposed at the slag collection outlet 112. At this time, the slag collection agitator 22 is located on the side of the slag collection filter screen 20 facing away from the slag collection outlet 112. It can be understood that the side of the slag collection filter screen 20 facing the slag collection outlet 112 is the side from which water flows out, and the side of the slag collection filter screen 20 facing away from the slag collection outlet 112 is the side from which slag is retained. The slag collection agitator 22 is located on the side of the slag collection filter screen 20 facing away from the slag collection outlet 112, which facilitates the agitator 22 stirring up the sediment, thereby facilitating the flow of the sediment towards the slag collection outlet 113, preventing the sediment from accumulating around the slag collection outlet 112 and clogging the slag collection filter screen 20, and preventing obstruction of the flow of water carrying sediment towards the slag collection outlet 112.

[0113] When a slag collection filter screen 20 is present in the slag collection chamber 11, the slag collection baffle 22 can be disposed on the slag collection filter screen 20 or on the inner wall surface of the slag collection chamber 11, for example, on the bottom wall surface S1 or the side wall surface S2 of the slag collection chamber 11. Alternatively, there can be multiple slag collection baffles 22, with some disposed on the slag collection filter screen 20 and some disposed on the inner wall surface of the slag collection chamber 11, thus providing multiple structural options for the slag collection baffle 22.

[0114] Understandably, since the slag-collecting agitator 22 is located on the side of the slag-collecting filter screen 20 opposite to the slag-collecting outlet 112, the agitator 22 can stir up the washing water while stirring the residue. The resulting washing water, when it washes over the slag-collecting filter screen 20, can wash away the residue on its surface. In other words, the agitated water flow can rinse the slag-retaining side of the slag-collecting filter screen 20, reducing residue clogging and improving its filtration efficiency. This reduces the frequency of replacing and cleaning the slag-collecting filter screen 20.

[0115] In some embodiments, the drive assembly 40 is connected to the sludge collection screen 20 to drive the sludge collection screen 20 to rotate. The drive assembly 40 provides power to drive the sludge collection screen 20 to rotate at high speed, and the high-speed rotation of the sludge collection screen 20 generates centrifugal force, so that the residue mixed in the sewage and the residue attached to the sludge collection screen 20 can be separated from the sludge collection screen 20 under the action of centrifugal force, which is beneficial to removing the residue clogging the mesh of the sludge collection screen 20.

[0116] It's understandable that conventional filters tend to get clogged after a period of use. To increase filtration capacity, the common practice is to increase the filter area, but this increases both cost and space requirements. Another method is to remove the filter and use a scraper to clean the residue clogging the mesh whenever the filtration efficiency drops. However, scraping compresses the filter, affecting its performance and lifespan. Furthermore, frequent scraping reduces the filter's resilience, making it more susceptible to deformation from water flow. This deformation can break off debris clogging the mesh, which then flows with the water to the collection outlet, causing secondary pollution and hindering cleaning.

[0117] In this application, when the drive component 40 drives the sludge collection filter screen 20 to rotate, the residue clogged on the sludge collection filter screen 20 can be shaken off, maintaining the filtration effect of the sludge collection filter screen 20. Moreover, without the scraper pressing, the service life of the sludge collection filter screen 20 can be extended, the frequency of cleaning the sludge collection filter screen 20 can be reduced, the probability of subsequent secondary pollution of the sludge collection filter screen 20 can be reduced, and the cleaning effect of the reuse of washing water can be improved.

[0118] In some embodiments, the filter device 100 further includes a rotatable slag-collecting filter screen 20, such as... Figure 4 As shown, the slag-collecting baffle 22 is mounted on the slag-collecting filter screen 20, allowing the slag-collecting filter screen 20 and the slag-collecting baffle 22 to operate simultaneously, achieving linkage. This simplifies the structure and improves compactness.

[0119] For example, when the slag-collecting baffle 22 is driven to rotate by water flow, the water flow also drives the slag-collecting filter screen 20 to rotate. The slag-collecting filter screen 20 does not need a separate drive component, which not only saves the number of parts but also improves energy efficiency. As another example, when a drive assembly 40 is connected to the slag-collecting baffle 22 to drive its movement, it can simultaneously drive the slag-collecting filter screen 20 to rotate.

[0120] Specifically, when the slag-collecting baffle 22 is installed on the slag-collecting filter screen 20, the slag-collecting baffle 22 is positioned near the bottom wall surface S1 of the slag-collecting chamber 11. This allows the slag-collecting baffle 22 to achieve a dual function: on the one hand, it can stir up the sediment at the bottom, preventing the sediment from sticking and allowing the sediment to mix with the washing water and flow downwards under the influence of the water flow. On the other hand, even when the water level is low, the slag-collecting baffle 22 near the bottom can still stir up the water flow, allowing the water to flow onto the surface of the slag-collecting filter screen 20 under the influence of the slag-collecting baffle 22, washing away the surface sediment, reducing the amount of sediment clogging the slag-collecting filter screen 20, and extending its service life.

[0121] In some embodiments, such as Figure 7 As shown, the slag collection filter 20 includes a first filter cylinder 21, which covers the slag collection outlet 112. The first filter cylinder 21 has a first mesh 211. The arrangement of the first filter cylinder 21 allows the slag collection filter 20 to achieve a large filtration area, enabling water to flow from 360 degrees to the slag collection outlet 112. Furthermore, all water flowing towards the slag collection outlet 112 must pass through the first filter cylinder 21 for filtration. The first filter cylinder 21 has a simple structure and low manufacturing cost.

[0122] It should be noted that the maximum particle size that can pass through the slag collection filter screen 20 can be limited by the size of the first mesh 211 on the first filter cylinder 21. For example, when the width of the first mesh 211 is set to 0.1 mm, the first filter cylinder 21 can retain residue with a particle size larger than 0.1 mm in the slag collection chamber 11, while residue with a particle size smaller 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 cylinder 21, with the first filter cylinder 21 being a rigid member to support the filter cloth, and the maximum particle size that can pass through the slag collection filter screen 20 is limited by the mesh size of the filter cloth.

[0123] like Figure 4 As shown, the slag-collecting and flow-deflecting element 22 is connected to the outer circumferential surface of the first filter cylinder 21 to guide the water flow on the outer circumferential surface of the first filter cylinder 21. When the slag-collecting filter screen 20 is rotatable, the structure of the first filter cylinder 21 ensures that the radial distance between various points on the first filter cylinder 21 and the slag-collecting outlet 112 is approximately the same, resulting in a uniform centrifugal force, which is beneficial for evenly dislodging residues from various parts of the surface. Optionally, the first filter cylinder 21 is a cylinder, and when the drive assembly 40 is running, the first filter cylinder 21 rotates around the center of the slag-collecting outlet 112.

[0124] The slag-collecting and flow-turbulence-inducing element 22 guides the water flow to flow along the outer circumference of the first filter cylinder 21. The function of the slag-collecting and flow-turbulence-inducing element 22 is to lengthen the water flow path along the outer circumference of the first filter cylinder 21, allowing it to impact more residue. Furthermore, the slag-collecting and flow-turbulence-inducing element 22 can guide the water flow to impact the residue on the first filter cylinder 21 tangentially, making it easier for the residue to be knocked off and detached from the first filter cylinder 21. This improves the slag removal and anti-clogging ability of the first filter cylinder 21.

[0125] In some specific embodiments, such as Figure 4 As shown, the sludge-collecting baffle 22 includes multiple sludge-collecting baffles 221 spaced circumferentially, which extend at an angle relative to the rotation axis of the sludge-collecting filter screen 20. This allows water flowing on the upper surface of the sludge-collecting baffles 221 to continue flowing upwards along them. When all the sludge-collecting baffles 221 rotate, they create an upward swirling flow on the surface of the sludge-collecting filter screen 20. This swirling flow has a large impact force, and each stream of water flows more persistently due to mutual influence, enhancing the impact force, extending the impact distance, and improving the sludge removal capability.

[0126] Specifically, such as Figure 4 As shown, the upper surface f1 of the slag-collecting baffle 221 is an arc-shaped surface, and the upper end of the slag-collecting baffle 221 gradually approaches a horizontal plane, which guides the water flow to rotate circumferentially. In this way, each stream of water pushes against the water flow on one side circumferentially, and each stream of water is pushed against the water flow on the other side circumferentially. All the water flows push against each other, which helps the water flow maintain swirling power, prolongs the rotational flow time, thereby enhancing the impact force of the water flow on the slag-collecting filter screen 20 and improving the cleaning ability of the filter slag.

[0127] Furthermore, such as Figure 6 As shown, the slag-collecting baffle 221 forms a single ring at the lower end of the slag-collecting filter screen 20, instead of multiple rings. This way, when the water flow is guided upward by the slag-collecting baffle 221, it will not encounter another ring of baffles that would obstruct the flow.

[0128] In some specific embodiments, such as Figure 6 and Figure 7 As shown, the slag collection screen 20 is vertically arranged, and a slag collection baffle 22 is provided at the bottom of the slag collection screen 20. In this way, the slag collection baffle 22 can prevent the residue from settling at the bottom of the slag collection chamber 11, and at the same time, it can make the slag collection screen 20 slender and tall, reducing resistance to water flow and reducing the space occupied by the slag collection.

[0129] With this setup, when the slag filter 20 is driven to rotate by the drive assembly 40, the drive assembly 40 can be set below or above the slag collection chamber 11, and can be set on the side wall S2 of the slag collection chamber 11 as much as possible, so as to avoid occupying too much area and making it unusable in the kitchen.

[0130] Specifically, such as Figure 7 As shown, the sludge collection outlet 112 is located on the bottom wall surface S1 of the sludge collection chamber 11. The sludge collection filter screen 20 is vertically arranged and covers the sludge collection outlet 112. The sludge collection filter screen 20 is higher than the bottom wall surface S1 of the sludge collection chamber 11 at least where the mesh is set. In this way, the filtered water can be quickly discharged from the sludge collection outlet 112 by utilizing the characteristics of water flow, and the residue is prevented from accumulating and clogging the mesh of the sludge collection filter screen 20.

[0131] In some specific embodiments, such as Figure 6 and Figure 8 As shown, the main structure 10 includes a platform 114 on the bottom wall surface S1 of the slag collection chamber 11. The platform 114 is arranged around the slag collection outlet 112. The slag collection filter screen 20 is arranged on the platform 114 so that the slag collection filter screen 20 is higher than the bottom wall surface S1 of the slag collection chamber 11.

[0132] The platform 114 raises the sludge collection screen 20 so that the lower edge of the sludge collection screen 20 is on the platform 114. This makes the gap between the two higher, preventing a large amount of bottom residue from flowing from the gap to the sludge collection outlet 112.

[0133] In some embodiments, such as Figure 11 As shown, the main body 10 has a slag collection and cleaning port 171 that connects to the slag collection chamber 11, such as... Figure 7 and Figure 8 As shown, the filter device 100 also includes a slag collection cover 62, which is closable and installed at the slag collection cleaning port 171. This allows for easy opening of the slag collection cover 62 during inspection or cleaning, enabling observation, cleaning, and maintenance through the slag collection cleaning port 171.

[0134] Here, the slag collection and cleaning port 171 is located on the top wall of the slag collection chamber 11, thus reducing the probability of leakage. Of course, it is also possible that in some designs, the slag collection and cleaning port 171 is located on the side wall surface S2 of the slag collection chamber 11.

[0135] Specifically, the projection of the slag collection filter screen 20 onto the surface of the slag collection and cleaning port 171 is entirely within the slag collection and cleaning port 171, and the slag collection filter screen 20 is detachably installed within the slag collection chamber 11. This facilitates the removal and extraction of the slag collection filter screen 20 from the slag collection and cleaning port 171, improving the convenience of maintenance and cleaning.

[0136] Furthermore, such as Figure 11 As shown, the edge of the slag collection cover 62 is provided with a first screw fastening structure 115 that matches the inner edge of the slag collection cleaning port 171, so that the slag collection cover 62 can be rotatably connected to the slag collection cleaning port 171. When in use, the slag collection cover 62 is screwed on to prevent it from being washed off by the water flow, and the slag collection cover 62 is screwed off when cleaning.

[0137] In some embodiments, such as Figure 7 and Figure 8 As shown, the slag collection screen 20 is rotatably connected to the slag collection cover 62 via the first bearing 64. This design, by using the slag collection cover 62 to support the rotation of the slag collection screen 20, improves rotational stability and prevents damage caused by the screen swinging during rotation.

[0138] In some embodiments, such as Figure 7As shown, the slag collection and cleaning port 171 is set opposite to the slag collection and water outlet 112, and the slag collection filter screen 20 is located at the slag collection and water outlet 112, making it convenient to directly remove the slag collection filter screen 20.

[0139] Specifically, the slag collection screen 20 is detachably connected to the drive assembly 40, so that when the slag collection cover 62 is opened, the slag collection screen 20 can be removed from the drive assembly 40. After maintenance is completed, the slag collection screen 20 can be reinstalled on the drive assembly 40.

[0140] Specifically, such as Figure 7 and Figure 8 As shown, the drive assembly 40 includes a drive component 41 and a first rotating shaft 42. The first rotating shaft 42 is vertically arranged, with one end connected to the drive component 41 and the other end connected to the slag collection filter screen 20. This allows the connection position between the first rotating shaft 42 and the slag collection filter screen 20 to be set according to the position of the rotation center of the slag collection filter screen 20.

[0141] Specifically, one end of the first rotating shaft 42 extends into the slag collection chamber 11 via the slag collection outlet 112, and the first rotating shaft 42 is connected to the slag collection filter screen 20. This facilitates the rotation of the slag collection filter screen 20 around the center of the slag collection outlet 112.

[0142] Furthermore, such as Figure 7 and Figure 4 As shown, the slag collection filter screen 20 also includes a first top cover 23 connected to the top of the first filter cylinder 21. The top cover 23 is fitted with a first rotating shaft 42. A first bearing 64 is fitted between the top cover 23 and the first rotating shaft 42. This can improve the torsional resistance of the slag collection filter screen 20, and the connection reliability is high, making the rotation more stable.

[0143] In some embodiments, such as Figure 2 and Figure 3 As shown, the main body 10 also includes a water purification chamber 12, which has a purification chamber inlet 121, a water purification outlet 122, and a waste outlet 123. The waste outlet 123 is connected to the slag collection inlet 111. The filtration device 100 also includes a water purification filter screen 30 installed on the water purification outlet 122.

[0144] In other words, in the direction of residue flow, the clean water chamber 12 is located upstream of the slag collection chamber 11. Washing water containing residue enters the clean water chamber 12 through the inlet 121, is filtered by the clean water filter screen 30, and then discharged from the clean water outlet 122. The remaining residue, containing a certain amount of moisture, is discharged from the waste outlet 123 to the slag collection chamber 11, where it undergoes further separation. The residue is then concentrated at the slag outlet 113 before being discharged. This initial filtration by the clean water filter screen 30 reduces the moisture content of the residue discharged into the slag collection chamber 11, facilitating centralized treatment of the residue.

[0145] In some embodiments, the filtration device 100 further includes a water purification agitator (not shown), which is disposed within the water purification chamber 12. The water purification agitator is located on the side of the water purification filter 30 opposite to the water purification outlet 122 and is adapted to agitate the water flow. That is, in the direction of water flow, the water purification agitator is located upstream of the water purification filter 30.

[0146] Specifically, the water purification agitator can stir the water flow within the water purification chamber 12, effectively preventing residue from accumulating inside. Simultaneously, the agitated water flow can rinse the upstream surface of the water purification filter screen 30, preventing residue from clogging it and thus improving the filtration efficiency of the filter device 100. The water flow, after being stirred by the agitator, can better carry the residue through the waste outlet 123 into the slag collection chamber 11 for centralized processing.

[0147] like Figure 11 As shown, the waste outlet 123 is higher than the bottom wall surface S6 of the purified water chamber 12. This prevents unfiltered water from rushing into the waste outlet 123 when the water flow is too rapid. Furthermore, with this arrangement, the waste outlet 123 is higher than the purified water outlet 122, ensuring that water flowing from the bottom of the purified water chamber 12 reaches the purified water outlet 122. This increases the water output of the purified water chamber 12.

[0148] Furthermore, the slag collection inlet 111 is higher than the bottom wall surface S1 of the slag collection chamber 11, which can prevent the residue in the slag collection chamber 11 from being directly impacted by the water flow and returning to the clean water chamber 12.

[0149] The water purification agitator not only facilitates automatic sludge removal from the filter device 100, effectively preventing residue buildup and clogging within the water purification chamber 12, but also effectively cleans residue adhering to the upstream surface of the water purification screen 30, preventing clogging and maintaining its filtration efficiency. Furthermore, the agitation of the upstream water flow by the agitator further enhances the filtration effect on residue.

[0150] When a water purification filter 30 is present in the water purification chamber 12, the water purification baffle can be disposed on the water purification filter 30, or on the inner wall surface of the water purification chamber 12, for example, on the bottom wall surface S6 or the side wall surface S5 of the water purification chamber 12. Alternatively, there can be multiple water purification baffles, with some disposed on the water purification filter 30 and some disposed on the inner wall surface of the water purification chamber 12, thus providing a variety of structural options for the water purification baffles.

[0151] The water purification baffle 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 baffle is located between the upstream side of the water purification screen 30 and the side wall S5 of the water purification chamber 12. This position can ensure that the water purification baffle can agitate the water flow on the upstream side of the water purification screen 30.

[0152] When the water purification agitator protrudes from the upstream surface of the water purification filter screen 30, it can more directly agitate the fluid and residual residue on the upstream side, making it easier for them to enter the sludge collection chamber 11 through the waste outlet 123. The protruding design increases the contact area between the water purification agitator and the fluid, thereby improving the agitation effect.

[0153] When the water purification baffle protrudes from the inner wall of the water purification chamber 12, after proper arrangement, it can not only agitate 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 towards the waste outlet 123, thereby improving the slag discharge efficiency.

[0154] When the water purification agitator is located between the upstream side of the water purification filter screen 30 and the inner wall of the water purification chamber 12, the water purification agitator can be rationally planned according to the actual size of the filter device 100, resulting in greater flexibility. For example, the filter device 100 can adjust the position, angle, or movement mode of the water purification agitator and optimize it according to different cleaning needs and usage scenarios to achieve the best agitation and sludge removal effect.

[0155] Specifically, such as Figure 3 As shown, the distribution of the clean chamber inlet 121 and the waste outlet 123 affects the separation effect. By distributing the clean chamber inlet 121 and the waste outlet 123 separately along the circumference of the clean water chamber 12, it is possible to prevent the separated residue from being mixed back into the water. It can also ensure that the residue is more evenly distributed in the clean water chamber 12 when it enters the clean water chamber 12, reducing the situation of excessive or insufficient local distribution, thereby improving the filtration efficiency and filtration effect.

[0156] In some specific embodiments, the water purification agitator is a movable component, and it is configured such that the water flow drives its movement. In other words, the water flow impact drives the water purification agitator, which can agitate the filter residue. The agitation action of the water purification agitator utilizes the kinetic energy of the water flow, eliminating the need for a separate drive component, thus saving on the number of parts and improving energy efficiency.

[0157] In some other embodiments, the filtration device 100 further includes a drive assembly 40, which is connected to the water purification agitator to drive its movement. This not only provides high controllability but also allows the agitator to move even when the water flow energy is insufficient, thus maintaining continuous agitation of the filter cake and further reducing the phenomenon of filter cake settling and adhering to the walls.

[0158] In some specific embodiments, the water purification baffle is rotatably disposed in the water purification chamber 12, and the drive assembly 40 is used to drive the water purification baffle to rotate, thus the structure of the drive assembly 40 is relatively simple.

[0159] In some embodiments, such as Figure 7 As shown, the drive assembly 40 is connected to the water purification filter screen 30 to drive the water purification filter screen 30 to rotate. The drive assembly 40 provides power to drive the water purification filter screen 30 to rotate at high speed, and the high-speed rotation of the water purification filter screen 30 generates centrifugal force, so that the residue mixed in the sewage and the residue attached to the water purification filter screen 30 can be separated from the water purification filter screen 30 under the action of centrifugal force. This not only facilitates the flow of residue to the waste outlet 123, but also helps to remove the residue clogging the mesh of the water purification filter screen 30.

[0160] When the drive component 40 drives the water filter screen 30 to rotate, the residue clogged on the water filter screen 30 can be shaken off, maintaining the filtration effect of the water filter screen 30. Moreover, without the scraper pressing, the service life of the water filter screen 30 can be extended, the frequency of cleaning the water filter screen 30 can be reduced, the probability of secondary pollution of the water filter screen 30 can be reduced, and the cleaning effect of reusing washing water can be improved.

[0161] In some embodiments, the filtration device 100 further includes a rotatable water purification filter screen 30, with a water purification baffle disposed on the water purification filter screen 30. This allows the water purification filter screen 30 and the water purification baffle to operate simultaneously, achieving linkage. This simplifies the structure and improves compactness.

[0162] Specifically, when the water purification baffle is installed on the water purification filter screen 30, it is positioned near the bottom wall surface S6 of the water purification chamber 12. This allows the water purification baffle to perform a dual function: firstly, it can stir up the sediment at the bottom, preventing it from sticking and allowing it to mix with the washing water and flow circumferentially under the influence of the water flow, thus flowing to the waste outlet 123. Secondly, when the water level is low, the near-bottom water purification baffle can stir up the water flow, allowing it to flow onto the surface of the water purification filter screen 30, washing away surface sediment, reducing the amount of sediment clogging the water purification filter screen 30, and extending its service life.

[0163] In some embodiments, such as Figure 7 As shown, the water purification filter 30 includes a second filter cartridge 31, which covers the purified water outlet 122. The second filter cartridge 31 has a second mesh 311. The second filter cartridge 31 allows the water purification filter 30 to achieve a larger filtration area, enabling water to flow from 360 degrees to the purified water outlet 122. All water flowing towards the purified water outlet 122 must pass through the second filter cartridge 31 for filtration. The second filter cartridge 31 has a simple structure and low manufacturing cost.

[0164] It should be noted that the maximum particle size that the water purification filter screen 30 can pass through 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 to 0.3 mm, the second filter cartridge 31 can retain residue with a particle size larger than 0.3 mm in the water purification chamber 12, which will flow with the water to the waste outlet 123. Residue with a particle size smaller than 0.3 mm may flow with the washing water to the water purification outlet 122. Alternatively, at least one layer of filter cloth can be provided on the surface of the second filter cartridge 31, with the second filter cartridge 31 being a rigid member to support the filter cloth, and the maximum particle size that the water purification filter screen 30 can pass through is limited by the mesh size of the filter cloth.

[0165] A water purification flow disruptor is connected to the outer circumferential surface of the second filter cartridge 31 to guide the water flow on the outer circumferential surface of the second filter cartridge 31. When the water purification filter screen 30 is rotatable, the structure of the second filter cartridge 31 ensures that the radial distance between various points on the second filter cartridge 31 and the water purification outlet 122 is approximately the same, thereby obtaining a consistent centrifugal force. Optionally, when the drive assembly 40 is operating, the second filter cartridge 31 rotates around the center of the water purification outlet 122.

[0166] The water-purifying baffle guides the water flow to the outer circumference of the second filter cartridge 31. The baffle lengthens the flow path along the outer circumference of the second filter cartridge 31, allowing it to impact more residue. Furthermore, the baffle guides the water flow tangentially to impact the residue on the second filter cartridge 31, making it easier for the residue to be knocked off and detached from the second filter cartridge 31. This improves the residue removal and anti-clogging capabilities of the second filter cartridge 31.

[0167] In some specific embodiments, the water purification baffle includes multiple water purification baffles spaced circumferentially, which extend at an angle relative to the rotation axis of the water purification filter screen 30. This allows water flowing on the upper surface of the baffles to continue flowing upwards along them. After all the baffles rotate, the water flow forms an upward swirling current on the surface of the water purification filter screen 30. This swirling impact force is large, and each stream of water flows more persistently due to mutual influence, enhancing the water flow impact force, extending the water flow impact distance, and improving the ability to remove filter residue.

[0168] Optionally, the upper surface of the water purification baffle is arc-shaped, and the upper end of the baffle gradually approaches a horizontal plane, which guides the water flow to rotate circumferentially. In this way, each stream of water pushes against the water flow on one side circumferentially, and each stream is pushed against the water flow on the other side circumferentially. All the water flows push against each other, which helps maintain the swirling momentum of the water flow, prolongs the rotational flow time, and thus enhances the impact force of the water flow on the water purification filter screen 30, improving the ability to clean filter residue.

[0169] Furthermore, the water purification baffle forms a single ring at the lower end of the water purification filter screen 30, instead of multiple rings. This way, when the water flow is guided upward by the water purification baffle, it will not encounter another ring of baffles that would obstruct the flow.

[0170] In some specific embodiments, the water purification filter screen 30 is arranged vertically, and a water purification baffle is provided at the bottom of the water purification filter screen 30. In this way, the water purification baffle can prevent the residue from settling at the bottom of the water purification chamber 12, and also make the water purification filter screen 30 slender and tall, reducing resistance to water flow and reducing the space occupied by the residue collection.

[0171] In some embodiments, such as Figure 11 As shown, the main body 10 has a cleanroom opening 172 that connects to the clean water chamber 12, as... Figure 7 and Figure 8 As shown, the filter device 100 also includes a clean chamber cover 63, which is closable and installable at the clean chamber cleaning port 172. This allows for easy opening of the clean chamber cover 63 during inspection or cleaning, enabling observation, cleaning, and maintenance through the clean chamber cleaning port 172.

[0172] Here, the cleaning port 172 is located on the top wall of the water purification chamber 12, thus reducing the probability of leakage. Of course, it is also possible that in some designs, the cleaning port 172 is located on the side wall surface S5 of the water purification chamber 12.

[0173] Specifically, the projection of the water purification filter 30 onto the surface of the cleaning port 172 of the purification chamber is entirely within the cleaning port 172, and the water purification filter 30 is detachably installed within the purification chamber 12. This facilitates the removal and extraction of the water purification filter 30 from the cleaning port 172, improving the convenience of maintenance and cleaning.

[0174] Furthermore, such as Figure 11 As shown, a second screw-on structure 125 is provided on the edge of the cleanroom cover 63 and the inner edge of the cleanroom opening 172 to cooperate, so that the cleanroom cover 63 can be rotatably connected to the cleanroom opening 172. When in use, the cleanroom cover 63 is screwed on to prevent it from being washed off by water flow, and the cleanroom cover 63 is screwed off when cleaning.

[0175] In some embodiments, such as Figure 7 and Figure 8 As shown, the water purification filter screen 30 is rotatably connected to the purification chamber cover 63 via the second bearing 68. This design, by using the purification chamber cover 63 to support the rotation of the water purification filter screen 30, improves rotational stability and prevents damage caused by the water purification filter screen 30 swinging during rotation.

[0176] In some embodiments, such as Figure 7 As shown, the cleanroom cleaning port 172 is positioned opposite to the clean water outlet 122, while the clean water filter 30 is located at the clean water outlet 122, making it convenient to remove the clean water filter 30 directly.

[0177] Specifically, the water filter screen 30 is detachably connected to the drive assembly 40, so that when the clean chamber cover 63 is opened, the water filter screen 30 can be removed from the drive assembly 40. After maintenance is completed, the water filter screen 30 can be reinstalled on the drive assembly 40.

[0178] Specifically, such as 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, with one end connected to the drive member 41 and the other end connected to the water purification filter screen 30. This allows the connection position between the second rotating shaft 43 and the water purification filter screen 30 to be set according to the position of the rotation center of the water purification filter screen 30.

[0179] Specifically, one end of the second rotating shaft 43 extends into the water purification chamber 12 via the purified water outlet 122, and the second rotating shaft 43 is connected to the purified water filter screen 30. This facilitates the rotation of the purified water filter screen 30 around the center of the purified water outlet 122.

[0180] Furthermore, such as Figure 7 and Figure 4 As shown, the water purification filter screen 30 also includes a second top cover 33 connected to the top of the second filter cartridge 31. The top cover 33 is fitted with a second rotating shaft 43. The second bearing 68 is fitted between the top cover 33 and the second rotating shaft 43. This can improve the torsional resistance of the water purification filter screen 30, and the connection reliability is high, and the rotation is more stable.

[0181] In some embodiments, the water purification turbulence element and the sludge collection turbulence element 22 are linked. This way, when one is driven to move, the other also moves synchronously, increasing the frequency of their movements and enhancing the turbulence effect.

[0182] For example, the water flow rate in the water purification chamber 12 is large, and the water purification baffle can move under the impact of the water flow, simultaneously driving the slag collection baffle 22 to move. As another example, the drive assembly 40 drives one of the moving parts, simultaneously driving the other moving part.

[0183] In some specific embodiments, such as Figure 7 As shown, both the sludge collection filter screen 20 and the water purification filter screen 30 are rotatably mounted on the main structure 10, and are linked together. The drive assembly 40 drives one of them to rotate, which in turn drives the other to rotate, thus saving one set of drive assemblies 40 and facilitating the arrangement of parts.

[0184] Furthermore, the drive assembly 40 is connected to at least one of the sludge collection filter screen 20 and the water purification filter screen 30 to drive the sludge collection filter screen 20 and the water purification filter screen 30 to rotate simultaneously. In other words, the sludge collection filter screen 20 and the water purification filter screen 30, as well as the water purification baffle and the sludge collection baffle 22, are all linked. Only one drive assembly 40 is needed to complete the movement of all four, reducing the number of parts and improving the compactness of the parts.

[0185] In some specific embodiments, such as Figure 7 and Figure 5 As shown, the drive assembly 40 includes a drive component 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 screen 20. The other end of the first rotating shaft 42 is poweredly connected to the drive component 41. One end of the second rotating shaft 43 extends into the water purification chamber 12 and is connected to the water purification filter screen 30. The other end of the second rotating shaft 43 is poweredly connected to the drive component 41. The two shafts connect to two filter screens, resulting in a simple structure that does not require excessive space.

[0186] In some embodiments, such as Figure 1 As shown, the filter device 100 also includes a flow channel plate 50, which is located at the bottom of the main body 10. The drive component 41 is mounted on the flow channel plate 50, thus reducing the processing and sealing difficulty of the main body 10.

[0187] Specifically, such as Figure 7 and Figure 8 As shown, the first rotating shaft 42 is vertically arranged, and its upper end extends into the sludge collection chamber 11 through the sludge collection outlet 112. The second rotating shaft 43 is vertically arranged, and its upper end extends into the clean water chamber 12 through the clean water outlet 122. This facilitates the rotation of the sludge collection filter screen 20 around the center of the sludge collection outlet 112 and the rotation of the clean water filter screen 30 around the center of the clean water outlet 122.

[0188] In some specific embodiments, such as Figure 7 and Figure 8 As shown, the flow channel plate 50 is provided with a gear groove 52, and the lower ends of the first rotating shaft 42 and the second rotating shaft 43 both extend into the gear groove 52. The drive assembly 40 also includes: a first gear 44 mounted on the first rotating shaft 42 and a second gear 45 mounted on the second rotating shaft 43. The first gear 44 and the second gear 45 mesh with each other, and the drive member 41 cooperates with one of the first gear 44 and the second gear 45. With this arrangement, the gear set used for linkage can be arranged in the flat gear groove 52, reducing the overall height dimension. In addition, gear transmission also facilitates the adjustment of the speed ratio according to the number of teeth, which helps the sludge collection filter screen 20 and the water purification filter screen 30 to obtain appropriate speeds.

[0189] In some embodiments, such as Figure 7 and Figure 8 As shown, the gear groove 52 is open downwards, and the filter device 100 also includes a gear cover 66 that fits into the bottom of the flow channel plate 50. This facilitates assembly, maintenance, and inspection.

[0190] In some embodiments, such as Figure 7 and Figure 6As shown, the drive component 41 is a drive motor 41a, which is vertically mounted on the flow channel plate 50. The drive motor 41a is located on the horizontal side of the main structure 10, and the lower end of the drive motor 41a has 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 allows for both speed reduction and torque increase, and also integrates the drive component 41 on the horizontal side of the main structure 10, preventing the entire filter device 100 from being too tall.

[0191] In some embodiments, such as Figures 1-9 As shown, the filter device 100 also includes a circulation pump 65. The inlet end 651 of the circulation pump 65 is connected to the sludge collection outlet 112. When the circulation pump 65 is working, it is used to draw in the water collected by the sludge collection outlet 112 and to make the sludge collection chamber 11 a negative pressure state. This can keep the residue in the sludge collection chamber 11 stationary under negative pressure, and avoid the sludge inlet 111 from being obstructed due to excessive air pressure in the sludge collection chamber 11.

[0192] In some embodiments, when the filter device 100 includes a circulation pump 65, the inlet 651 of the circulation pump 65 is also connected to the purified water outlet 122. When the circulation pump 65 is in operation, it is used to draw in water collected at the purified water outlet 122 to complete the circulation and use of the washing water.

[0193] Specifically, such as Figure 8 As shown, when the circulating pump 65 is working, the slag discharge valve 61 closes the slag collection and discharge port 113; 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.

[0194] Specifically, the slag discharge valve 61 is a one-way valve 61a that opens unidirectionally from the slag collection chamber 11 outwards. The one-way valve 61a is controlled to open and close by the pressure difference between the two sides. At this time, the circulating pump 65 is used to control the air pressure inside.

[0195] In some embodiments, such as Figure 7 and Figure 8 As shown, a purified water channel 51 is provided inside the flow channel plate 50, which connects the sludge collection outlet 112 and the purified water outlet 122. Here, a single purified water channel 51 connects both the sludge collection outlet 112 and the purified water outlet 122, reducing the number of channels and simplifying the internal structure of the flow channel plate 50. The inlet end 651 of the circulation pump 65 is connected to the purified water channel 51. Thus, the purified washing water can flow through the purified water channel 51 to the circulation pump 65 for recycling.

[0196] In some embodiments, such as Figure 7 and Figure 8As shown, the filtration device 100 further includes a backwash member 55, which is disposed within the water purification chamber 12. The backwash member 55 has a backwash channel 551 within it, and a spray hole 552 communicating with the backwash channel 551 and facing the water purification filter screen 30. Water sprayed from the backwash member 55 through the spray hole 552 is sprayed onto the water purification filter screen 30, which can remove residue stuck on the water purification filter screen 30, improve the filtration capacity of the water purification filter screen 30, and extend its service life.

[0197] Specifically, the water purification filter screen 30 covers the backwash member 55, which is located downstream of the water purification filter screen 30, i.e., on the side of the water purification filter screen 30 facing the water purification outlet 122. When the backwash member 55 sprays water onto the water purification filter screen 30, any residue stuck on the screen falls to the upstream side, facilitating discharge from the waste outlet 123.

[0198] Optionally, such as Figure 8 As shown, the backflushing member 55 is provided with a plurality of spray holes 552 arranged along the rotation axis of the water purification filter 30. The washing water sprayed from these plurality of spray holes 552 forms a jet line extending along the rotation axis of the water purification filter 30. The jet line from the plurality of spray holes 552 is long enough to effectively spray away the residue stuck on the water purification filter 30.

[0199] In some embodiments, the filtration device 100 further includes a circulation pump 65, the inlet end 651 of which is connected to the sludge collection outlet 112 and the purified water outlet 122, and the outlet end 652 of which is connected to the backwash channel 551. The washing water filtered by the purified water filter screen 30 in the purified water chamber 12 can directly enter the circulation pump 65 through the inlet end 651, increasing the flow rate of the washing water between the circulation pump 65 and the purified water chamber 12, thus improving the circulation efficiency of the washing water. The backwash member 55 is housed in the purified water chamber 12 and located upstream of the purified water filter screen 30. The backwash member 55 is connected to the outlet end 652 of the circulation pump 65, allowing the filtered washing water in the purified water chamber 12 to enter the inlet end 651 of the circulation pump 65. The backwash member 55 has a spray hole 552 that opens toward the water purification filter screen 30. The washing water flowing into the backwash member 55 can be sprayed onto the water purification filter screen 30 through the spray hole 552 to remove the filter residue adhering to the surface of the water purification filter screen 30, reduce the possibility of clogging of the water purification filter screen 30, improve the cleanliness and permeability of the water purification filter screen 30, reduce the loss of washing water, and improve the filtration efficiency and filtration effect of the water purification filter screen 30.

[0200] Specifically, such as Figure 8As shown, the filtration device 100 further includes: a flow channel plate 50, which is located at the bottom of the main structure 10. The flow channel plate 50 contains a purified water flow channel 51, which connects to the sludge collection outlet 112 and the purified water outlet 122. A backflushing component 55 is located at the top of the flow channel plate 50, and the flow channel plate 50 contains a water supply channel 53 that connects to the backflushing flow channel 551. Here, using the flow channel plate 50 to connect the backflushing component 55 results in high integration and convenient assembly, reduces the number of parts, and facilitates sealing.

[0201] Furthermore, the backflush member 55 is integrally formed on the top of the flow channel plate 50, and the flow channel plate 50 is provided with a water supply channel 53 that connects to the backflush channel 551. That is, the outlet end 652 of the circulating pump 65 is connected to the water supply channel 53, and then the water flows from the water supply channel 53 to the backflush channel 551. This eliminates the need for additional piping and simplifies the structure.

[0202] Specifically, such as Figure 2 As shown, the washing water flowing out from the outlet 652 of the circulating pump 65 will be split into two flows. Most of the washing water flows to the washing stage, and a small portion flows into the diversion pipe 56. The other end of the diversion pipe 56 is connected to the main structure 10 and is connected to the water supply channel 53, thereby supplying the split washing water to the backwashing member 55.

[0203] In some embodiments, such as Figure 9 and Figure 11 As shown, a circulating water pipe 193 is provided at the bottom of the main body 10. A spray arm channel 15 is provided inside the main body 10. The lower end of the spray arm channel 15 is connected to the circulating water pipe 193, and the upper end of the spray arm channel 15 forms a spray arm interface 151 at the top of the main body 10. This arrangement facilitates the flow of filtered washing water into the circulating water pipe 193 via the driving of the circulating pump 65, and then into the spray arm channel 15 from the circulating water pipe 193.

[0204] The spray arm interface 151 here is used to install a spray arm, which can be a fixed arm or a rotating arm. By introducing washing water, the spray arm can spray washing water onto items to be washed, such as pots and pans, to improve cleanliness.

[0205] Specifically, the main body 10 is provided with at least two spray arm channels 15. In order to ensure that each spray arm channel 15 can obtain a certain amount of washing water, the filter device 100 also includes a water distribution valve 69. The water distribution valve 69 is connected to the circulating water pipe 193 to distribute the incoming water evenly to different spray arm channels 15.

[0206] More specifically, one end of the diversion pipe 56 is connected to the circulating water inlet pipe 193 and is located upstream of the diversion valve 69.

[0207] In some embodiments, such as Figure 9 and Figure 10As shown, the main body 10 is provided with a water collection chamber 14, which is used to collect the washing water of the cleaning equipment 1000. This makes it easy for the washing water to be collected in the water collection chamber 14 and discharged after the final washing is completed.

[0208] Specifically, the water collection chamber 14 is connected to the slag collection outlet 113, so that the residue collected in the slag collection chamber 11 can be discharged from the water collection chamber 14 along with the collected washing water. This allows the force of the washing water to flush out the residue, reducing the phenomenon of residue sticking to the wall during the flushing process.

[0209] Furthermore, such as Figure 9 and Figure 10 As shown, the water collection chamber 14 and the slag collection chamber 11 are separated by a one-way valve 61a, which opens unidirectionally from the slag collection chamber 11 to the water collection chamber 1. This allows the water collection chamber 14 to have a slightly higher air pressure than the slag collection chamber 11 when it is not draining, thus closing the slag outlet 113 of the one-way valve 61a. Especially when the cleaning equipment 1000 is in washing mode and the circulating pump 65 is running, putting the slag collection chamber 11 under negative pressure, the water collection chamber 14, which is not draining, has a higher air pressure than the slag collection chamber 11, thus tightly closing the slag outlet 113. This results in less residue in the washing water collected in the water collection chamber 14, facilitating collection and reuse. Meanwhile, the slag collection chamber 11 remains in a continuous slag collection and filtration state.

[0210] When the water collection chamber 14 drains water, the air pressure on one side of the water collection chamber 14 drops rapidly due to the rapid emptying. When the air pressure on one side of the water collection chamber 14 is lower than the air pressure on the other side of the slag collection chamber 11, the one-way valve 61a can be opened so that the collected residue can be discharged from the slag outlet 113 to the water collection chamber 14 and then discharged from the water collection chamber 14.

[0211] In some embodiments, the water collection chamber 14 and the slag collection chamber 11 are separated by a one-way valve 61a. When the circulation pump 65 is turned off and the water collection chamber 14 drains water, the slag collection chamber 11 is under positive pressure to open the one-way valve 61a. The start of the circulation pump 65 signifies the start of the washing process, and the shutdown of the circulation pump 65 signifies the end of the washing process. The opening and closing of the one-way valve 61a can be adjusted immediately by the opening and closing of the slag collection chamber 11, making the slag discharge control very flexible and eliminating the need for a separate controller.

[0212] The lowest point of the water collection chamber 14 is set below the slag discharge port 113 to facilitate the emptying of residue in the slag collection chamber 11 and reduce the accumulation at the slag discharge port 113.

[0213] In some embodiments, such 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 stepped surface 141 is formed at the connection. The one-way valve 61a is installed on the first stepped 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.

[0214] In some specific embodiments, such as Figure 11 As shown, the main body 10 is also provided with a drain outlet 175, which is connected to the slag collection and discharge outlet 113. A one-way valve 61a is provided at the slag collection and discharge outlet 113. The one-way valve 61a is configured to open in one direction from the slag collection chamber 11 to the drain outlet 175. That is to say, the residue is finally discharged from the drain outlet 175 during slag discharge.

[0215] Specifically, such as Figure 2 As shown, the water collection chamber 14 is connected to the drain outlet 175, and the filter device 100 also includes a drain valve 67 for opening and closing the drain outlet 175. When the circulation pump 65 is operating, the drain valve 67 is closed; when the drain valve 67 is open, the circulation pump 65 is closed. Thus, when the circulation pump 65 is operating, the slag collection chamber 11 is under negative pressure. At this time, the drain valve 67 is closed, and the water pressure in the water collection chamber 14 is high, thus closing the one-way valve 61a. When the circulation pump 65 is closed, the air pressure in the slag collection chamber 11 rises. At this time, the drain valve 67 opens, causing the water pressure in the water collection chamber 14 to decrease, allowing the residue to be automatically drawn into the water collection chamber 14 and finally flushed away by the water flow from the drain outlet 175.

[0216] In some embodiments, such as Figure 3 As shown, the main body 10 also includes a primary filtration chamber 13, which has a primary filtration outlet 133 connected to the clean chamber inlet 121. The filtration device 100 also includes a primary filter element 70, which is used to filter the washing water entering the primary filtration chamber 13.

[0217] In other words, before the residue enters the sludge collection chamber 11 with the water flow, it undergoes at least two filtrations. This allows the residue to be selected according to size, reducing the load on the filter screen during each filtration and improving the filtration effect.

[0218] Specifically, such as Figure 2 , Figure 3 and Figure 9 As shown, the primary filtration chamber 13 further includes: a primary filtration vertical chamber 131, and a primary filtration outlet 133 located on the outer peripheral wall of the primary filtration 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 in the primary filter chamber 13. The outer portion of the primary filter cup 71 forms the primary filter vertical chamber 131, and the inner portion of the primary filter cup 71 forms the unfiltered primary collection chamber 16. That is, the primary filter cup 71 uses the entire cylindrical wall for filtration, resulting in a large filtration area and high filtration efficiency. At this time, the washing water that has passed through the primary filter enters the clean water chamber 12 from the primary filter outlet 133 on the outer periphery of the primary filter vertical chamber 131. The incoming water flow has flow momentum, washing away the residue and flowing towards the waste outlet 123 to enter the sludge collection chamber 11.

[0219] It should be noted that the maximum particle size that can pass 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 larger than 0.5 mm in the primary collection chamber 16, while residue with a particle size smaller than 0.1 mm may flow into the primary filter vertical chamber 131 with the washing water and enter the clean water 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, and the maximum particle size that can pass through the primary filter cup 71 is limited by the mesh size of the filter cloth.

[0220] Furthermore, such as 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 71. The primary filter bottom wall 73 and the primary filter cup 71 form a filter cup, so that the large-sized residues filtered out can be concentrated in the filter cup for easy centralized cleaning.

[0221] It should be noted that the maximum particle size that can pass through 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 to 3 mm, the primary filter bottom wall 73 can retain residue with a particle size larger than 3 mm in the primary collection chamber 16. However, larger residues with a particle size smaller than 3 mm (residues smaller than the maximum particle size that can pass through the primary filter cup 71) may pass through the primary filter cup 71 and flow into the primary filter vertical chamber 131 with the washing water, entering the clean water chamber 12. Alternatively, at least one layer of filter cloth can be provided on the surface of the primary filter bottom wall 73, with the primary filter bottom wall 73 being a rigid member to support the filter cloth, and the maximum particle size that can pass through the primary filter bottom wall 73 is limited by the mesh size of the filter cloth.

[0222] Furthermore, such as 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 main body 10. The primary filter plate 72 is provided with a clearance opening 721, and the primary filter plate 72 is fitted onto the primary filter cup cylinder 71 through the clearance opening 721. The primary filter cavity 13 further includes a primary filter horizontal cavity 132 located between the primary filter plate 72 and the top surface of the main body 10. The primary filter horizontal cavity 132 is connected to the upper end of the primary filter vertical cavity 131.

[0223] This allows the washing water to pass through the primary filter plate 72 and enter the primary filter horizontal chamber 132, then the primary filter vertical chamber 131, and finally the purified water chamber 12 for filtration. This arrangement results in a large primary filtration area, fast filtration speed, and high efficiency.

[0224] It should be noted that the maximum particle size that can pass 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 to 0.5 mm, the primary filter plate 72 can retain residue with a particle size larger than 0.5 mm at the top, while residue with a particle size smaller than 0.5 mm may flow into the primary filter horizontal chamber 132 with the washing water and enter the clean water chamber 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, and the maximum particle size that can pass through the primary filter plate 72 is limited by the mesh size of the filter cloth.

[0225] In some specific embodiments, such as Figure 7 As shown, the pre-filter 70 also includes a cup rim 74 connected to the upper edge of the pre-filter cup cylinder 71, and the cup rim 74 is located above the pre-filter plate 72. The cup rim 74 refers to the rim of the filter cup, and the cup rim 74 is provided to facilitate the user to remove the filter cup for cleaning.

[0226] The connection between the cup rim 74 and the primary filter cup 71 is fitted into the clearance opening 721 of the primary filter plate 72. Optionally, the shape and size of the primary filter element 70 at the connection between the cup rim 74 and the primary filter cup 71 are consistent with the clearance opening 721, thereby achieving a relatively sealed connection to prevent residue leakage.

[0227] Furthermore, a slag passage hole 704 is provided on the rim 74 of the cup, which facilitates the water flow to carry the residue through the slag passage hole 704 and into the primary collection chamber 16. The size of the slag passage hole 704 is set relatively large here, which makes it convenient for all the larger residues to be collected in the primary collection chamber 16 for centralized treatment, which can reduce the amount of residue left above the primary filter plate 72 and avoid the residues left behind affecting the washing effect.

[0228] Specifically, the cup rim 74 is annular, and a ring of slag passage holes 704 is provided on the cup rim 74.

[0229] In some embodiments, such as Figure 2 and Figure 3 As shown, the primary filter cup 71, the water purification filter screen 30, and the sludge collection filter screen 20 are arranged in a triangular pattern. This allows the space required by the main structure 10 for these three components to be concentrated in one location. On the one hand, the external dimensions of the main structure 10 can be reduced, and on the other hand, the wall thickness of the partition between adjacent chambers can be controlled, which helps to reduce weight.

[0230] Specifically, such as Figure 9 As shown, the main body 10 is provided with a water collecting cavity 14, which is located below the primary collecting cavity 16. In this way, the water collecting cavity 14 can collect the washing water from the primary collecting cavity 16. On the one hand, this method of water collection after washing results in a short water flow path and fast water collection. On the other hand, it facilitates the processing and shaping of the water collecting cavity 14 and the primary collecting cavity 16.

[0231] More specifically, the water collecting chamber 14 is located below the primary collecting chamber 16, and the water collecting chamber 14 and the primary collecting chamber 16 are separated by the primary filter bottom wall 73. Thus, residue with a particle size exceeding the maximum passing particle size of the primary filter bottom wall 73 remains in the primary collecting chamber 16, i.e., in the filter cup. Residue with a particle size smaller than the maximum passing particle size of the primary filter bottom wall 73 can fall into the water collecting chamber 14. In this way, some residue accumulates in the water collecting chamber 14 during the washing process, and this residue can be discharged with the water flow after washing is completed.

[0232] Optionally, the water collection chamber 14 is located below both the primary collection chamber 16 and the primary filtration vertical chamber 131. During the operation of the filtration device 100, water flows from the cleaning space 201 through the primary filter and into the primary filtration vertical chamber 131, driven by the circulation pump 65. The filtered washing water, carrying small-diameter residue, enters the clean water chamber 12. Most of the washing water is filtered again and returns to the circulation pump 65, while a small portion, carrying a large amount of filtered small-diameter residue, enters the residue collection chamber 11. In the residue collection chamber 11, the washing water is filtered again, and the filtered washing water returns to the circulation pump 65, while the remaining residue remains in the residue collection chamber 11. During the filtration process, some residue in the primary collection chamber 16 sinks 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 filtration chamber 13, participating in the circulation of washing water. After the final filtration device 100 is used, the washing water can flow to the water collection chamber 14 and be discharged from the water collection chamber 14, carrying away the residue in the water collection chamber 14 and the residue collection chamber 11 at the same time. Larger residues remain in the filter cup and are manually removed and emptied.

[0233] In this application, the main chamber structures of the filter device 100 are all machined and formed on the main body 10. That is to say, the main body 10 is the main structure supporting the function of the filter device 100. To better understand the function of the filter device 100, refer to the following... Figure 11 The structure of the main body 10 of the embodiments of the present invention is described in the accompanying drawings and other related drawings.

[0234] According to an embodiment of the present invention, the main body 10 includes a horizontally arranged primary filtration vertical chamber 131, a purified water chamber 12, and a sludge collection chamber 11. As described above, the primary filtration vertical chamber 131 can be fitted with a primary filtration cup 71 for initial filtration. The purified water chamber 12 can be fitted with a purified water filter screen 30 for secondary filtration, and the sludge collection chamber 11 is used to collect the residue left after filtration. The main body 10 also includes a water collection chamber 14 for collecting washing water flowing into the other chambers, thus facilitating centralized drainage.

[0235] The primary filtration chamber 131 has a primary filtration outlet 133 on its side wall S7. The purified water chamber 12 has a purified water inlet 121, a purified water outlet 122, and a waste outlet 123. The purified water inlet 121 is connected to the primary filtration outlet 133. (Refer to...) Figure 11 and Figure 9 The slag collection chamber 11 has a slag collection inlet 111 and a slag collection outlet 113. The slag collection inlet 111 is connected to the waste outlet 123, and the slag collection outlet 113 is connected to the water collection chamber 14 to discharge slag when the water collection chamber 14 drains water. The separated clean washing water can be discharged from the clean water outlet 122 for recycling.

[0236] Arranging the primary filtration chamber 131, the purified water chamber 12, and the slag collection chamber 11 horizontally can reduce the overall height occupied and help control the height of the main structure 10.

[0237] Specifically, such as Figure 6 As shown, the bottom wall surface S1 of the slag collection chamber 11 includes a guide bottom surface S11, the height of which gradually decreases in the direction toward the slag collection outlet 113, and the lowest point of the water collection chamber 14 is lower than the slag collection outlet 113. This ensures smooth discharge of residue from the slag collection chamber 11 to the water collection chamber 14, increasing the probability of emptying the slag collection chamber 11.

[0238] In some embodiments, such as Figure 2 and Figure 11 As shown, a portion of the main structure 10 is a converging wall column 180, around which the primary filtration vertical chamber 131, the purified water chamber 12, and the sludge collection chamber 11 are arranged. The primary filtration vertical chamber 131, the purified water chamber 12, and the sludge collection chamber 11 are roughly triangularly distributed, and their close arrangement occupies little space, which helps to reduce the overall size of the main structure 10. This arrangement allows the residue to circulate within a relatively small space with the water flow, resulting in a long flow path, which allows the washing water to be fully separated and discharged during the flow.

[0239] In some embodiments, the portion of the main body 10 that separates the primary filtration vertical cavity 131 and the purified water cavity 12 is a first wall panel 181, such as... Figure 2 and Figure 11 As shown, one end of the first wall panel 181 is connected to the converging wall column 180, and the primary filter outlet 133 and the clean chamber inlet 121 are located on the first wall panel 181.

[0240] The portion of the main structure 10 that separates the water purification chamber 12 and the slag collection chamber 11 is a second wall panel 182. One end of the second wall panel 182 is connected to the converging 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 flow to smoothly carry unfiltered residue from the primary filtration vertical chamber 131 to the water purification chamber 12 and the slag collection chamber 11 during the sequential transverse flow from one chamber to another, reducing turbulence and thus reducing water flow resistance and energy consumption.

[0241] In some embodiments, such as Figure 2 and Figure 11As shown, the waste outlet 123 and the slag collection inlet 111 are located at the end of the second wall panel 182 away from the confluence wall column 180.

[0242] By positioning the waste outlet 123 at the end of the second wall panel 182 furthest from the confluence wall column 180 and at a greater circumferential distance from the clean chamber inlet 121, the probability of filtered residue flowing back from the clean chamber inlet 121 can be reduced. Furthermore, the slag discharge channel 184 between the waste outlet 123 and the slag collection inlet 111 can be shorter, facilitating processing and reducing the likelihood of residue clogging the slag discharge channel 184.

[0243] In some embodiments, such as Figure 11 As shown, the first wall panel 181 is provided with an exhaust hole 124 that connects the primary filtration vertical chamber 131 and the purified water chamber 12. This can balance the air pressure inside and outside the purified water chamber 12, allowing the washing water filtered out by the primary filtration vertical chamber 131 to smoothly enter the purified water chamber 12.

[0244] Specifically, such as Figure 11 As shown, the vent 124 is higher than the primary filter outlet 133, so that the water flow in the primary filter vertical chamber 131 flows from the primary filter outlet 133 to the clean water chamber 12, and the water flow height is roughly within the height range of the primary filter outlet 133. The fact that the vent 124 is higher than the primary filter outlet 133 can prevent water from flowing into the vent 124 and causing a water seal.

[0245] Specifically, such as Figure 11 As shown, the vent 124 is located on the side of the primary filter outlet 133 near the confluence wall column 180. It can be understood that, according to the design, the water flow in the purified water chamber 12 flows circumferentially from the chamber inlet 121 towards the waste outlet 123. During this flow, a large amount of washing water flows radially towards the central purified water outlet 122. The vent 124 is located on the side of the primary filter outlet 133 near the confluence wall column 180. In the direction of water flow within the purified water chamber 12, the vent 124 is downstream of the chamber inlet 121 and waste outlet 123, reducing the probability of water and residue flowing towards the vent 124, thus lowering the probability of clogging.

[0246] In some embodiments, the slag collection inlet 111 is located on the side wall surface S2 of the slag collection chamber 11 and is higher than the slag collection 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.

[0247] In some embodiments, the sidewall of the slag collection chamber 11 opposite to the slag collection inlet 111 is a first arc-shaped surface S3-1. The two ends of the first arc-shaped surface S3-1 correspond to the slag collection inlet 111 and the slag collection outlet 113, respectively. The middle two ends of the first arc-shaped surface S3-1 protrude in a direction away from the slag collection outlet 112. Thus, when the water flow is fast, carrying the residue from the slag collection inlet 111 into the slag collection chamber 11, the residue is sprayed onto the first arc-shaped surface S3-1, thereby concentrating along the first arc-shaped surface S3-1 towards the slag collection outlet 113. This facilitates improved residue concentration efficiency by utilizing the first arc-shaped surface S3-1.

[0248] 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 slag entry, while the smaller slag collection outlet 113 is easy to close and easy to adjust the slag collection chamber 11 to a negative pressure state.

[0249] In some embodiments, the horizontal projection of the slag collection chamber 11 is elongated. The side wall surface S2 of the slag collection chamber 11 includes a first side wall surface S21, a second side wall surface S22, a third side wall surface S23, and a fourth side wall surface S24 connected in sequence. The first side wall surface S21 and the third side wall surface S23 are arranged opposite to each other, and the second side wall surface S22 and the fourth side wall surface S24 are arranged opposite to each other.

[0250] The primary filtration chamber 131 and the purified water chamber 12 are located on the side of the first side wall S21 that is 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.

[0251] This arrangement makes the three cavities occupy a space that is close to a rectangle, which facilitates the processing of the main structure 10.

[0252] In some embodiments, the water purification filter screen 30 is rotatably disposed within the water purification chamber 12, and the rotation direction of the water purification filter screen 30 is tangentially oriented towards the slag collection inlet 111 at the waste outlet 123. Thus, when the residue ejected from the water purification filter screen 30 slides along the side wall S5 of the water purification chamber 12, it can slide along the waste outlet 123 towards the slag collection inlet 111 and enter the slag collection chamber 11. This facilitates the smooth entry of residue into the slag collection chamber 11, reducing residue accumulation within the water purification chamber 12.

[0253] In some embodiments, such as Figure 3As shown, the slag collection inlet 111 is located on the first side wall S21, and the edge of the slag collection inlet 111 is located on the second side wall S22. That is to say, when water carries slag in, it can smoothly slide onto the second side wall S22, increasing the sliding speed of the slag along the wall, which helps the slag to continue to concentrate towards the slag collection outlet 113.

[0254] In some embodiments, such 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.

[0255] The second side wall 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.

[0256] Here, the cylindrical shape of the water purification chamber 12 helps to obtain a stable centrifugal force when the water flows along the side wall S5 of the water purification chamber 12 with the residue, thereby helping the residue to be thrown out from the waste outlet 123 after encountering the waste outlet 123.

[0257] 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 diameter L1. The slag discharge channel 184 is positioned approximately tangentially to the water purification chamber 12, which coincides with the inertial force gained by the residue at the waste outlet 123, allowing the residue to be quickly discharged into the slag collection chamber 11 along the slag discharge channel 184. This arrangement ensures that the residue enters the slag collection chamber 11 at a relatively high speed, allowing it to concentrate towards the slag collection outlet 113 under the action of inertial force, thus improving slag collection efficiency.

[0258] In some specific embodiments, such as Figure 3 As shown, the third side wall S23 is the first arc-shaped surface S3-1, with its two opposite ends protruding in a direction away from the intersecting wall column 180. (See diagram below.) Figure 2 As shown, when the water flow is fast, it carries the residue from the residue inlet 111 into the residue collection chamber 11. The residue is sprayed onto the first arc-shaped surface S3-1, and thus concentrates along the first arc-shaped surface S3-1 towards the residue outlet 113. In this way, the first arc-shaped surface S3-1 is used to improve the concentration efficiency of the residue.

[0259] In some specific embodiments, such as Figure 3 As shown, the first sidewall S21 is the second arc-shaped surface S1-1. (As...) Figure 2 As shown, the second arc-shaped surface S1-1 forms a convex angle 185 protruding towards the confluence wall column 180 at the confluence wall column 180, which can expand the capacity of the slag collection chamber 11.

[0260] Specifically, the sludge collection chamber 11 also has a sludge collection outlet 112 located on the bottom wall surface S1 of the sludge collection chamber 11, which is positioned near the convex corner 185. When the water flows into the convex corner 185, its velocity decreases, making it easier to flow out from the sludge collection outlet 112. Furthermore, when the sludge collection outlet 112 is located here, a sludge collection filter screen 20 can also be installed here. The convex corner 185 provides space for the sludge collection filter screen 20 to move, which helps to increase the filtration area of ​​the sludge collection filter screen 20 and improve the filtration effect.

[0261] In some specific embodiments, such as Figure 6 and Figure 8 As shown, the main structure 10 includes a platform 114 on the bottom wall surface S1 of the slag collection chamber 11, which surrounds the slag collection outlet 112. This allows the slag collection filter screen 20 to be higher than the bottom wall surface S1 of the slag collection chamber 11, reducing the amount of bottom residue flowing from the gaps below the slag collection filter screen 20 to the slag collection outlet 112.

[0262] In some specific embodiments, the waste outlet 123 is higher than the bottom wall surface S6 of the water purification chamber 12. This can prevent the residue in the slag collection chamber 11 from being directly impacted by the water flow and returning to the water purification chamber 12.

[0263] In some specific embodiments, such as Figure 11 As shown, the top of the main body 10 is provided with a slag collection cleaning port 171 that connects to the slag collection chamber 11 and a clean water chamber cleaning port 172 that connects to the clean water chamber 12. This makes it convenient to observe, clean, and maintain the equipment through the slag collection cleaning port 171 and the clean water chamber cleaning port 172 during inspection or cleaning.

[0264] In some specific embodiments, the top of the primary filtration vertical cavity 131 is open to facilitate the assembly of the filter cup.

[0265] The top edge of the main body 10 forms a fitting flange 192, which encloses a primary filtration horizontal cavity 132 between the fitting flange 192 and the top surface of the main body 10. The primary filtration horizontal cavity 132 is connected to the upper end of the primary filtration vertical cavity 131. This facilitates the installation of the primary filter plate 72 using the fitting flange 192, ultimately positioning the primary filter plate 72 at the top of the main body 10. This allows washing water to be quickly filtered through the primary filter plate 72 from above and enter the primary filtration horizontal cavity 132.

[0266] In some specific embodiments, such as 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 main body 10 that separates the water collection chamber 14 and the slag collection chamber 11 is a third wall plate 183, and the slag discharge port 113 is located on the 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 facilitates weight reduction and shortens the slag discharge path, which is beneficial for emptying the residue in the slag collection chamber 11.

[0267] In some specific embodiments, such as Figure 10 As shown, the bottom wall surface S3 of the water collecting cavity 14 is lower than the bottom wall surface S1 of the slag collecting cavity 11, and a first stepped surface 141 is formed at the connection. This facilitates the emptying of the residue in the slag collecting cavity 11 and also makes it easier to position the slag discharge valve 61 using the first stepped surface 141, thus improving the assembly convenience of the slag discharge valve 61.

[0268] Specifically, the connection between the side wall S4 of the water collection chamber 14 and the side wall S7 of the primary filter vertical chamber 131 forms an inner connection 142, which facilitates the placement of the primary filter cup 71 on the inner connection 142. The inner connection 142 serves as the installation and positioning part for the primary filter cup 71, making filter cup installation convenient.

[0269] Specifically, the inner part 142 extends radially along the primary filter vertical cavity 131, which has a simple structure and is easy to assemble smoothly.

[0270] Furthermore, the inner part 142 is annular and has a snap-fit ​​opening. The primary filter element 70 includes a buckle on the outer circumferential surface of the primary filter cup 71, and the buckle is engaged in the snap-fit ​​opening.

[0271] In some specific embodiments, such as Figure 11 As shown, a drain pipe 191 is provided on the outer side of the main 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 a drain valve 67. A drain outlet 175 is provided on the pipe wall of the drain pipe 191. This arrangement facilitates the assembly of the drain valve 67.

[0272] In some specific embodiments, such as Figure 9 As shown, the main body 10 is provided with a water inlet 194, which is located on the peripheral wall of the primary filter vertical cavity 131 to facilitate the introduction of water flow.

[0273] like Figure 12 As shown, the 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 filtration device 100 described in the above embodiment. The structures of the structural body 10 and the filtration device 100 will not be described in detail here. The cleaning device 1000 further includes: a device body 200. The structural body 10 is integrated into the device body 200, and the device body 200 forms a cleaning space V1.

[0274] Specifically, the main structure 10 contains a slag collection chamber 11, which is located below the cleaning space V1, and the bottom of the cleaning space V1 is connected to the slag collection inlet 111. Alternatively, the main structure 10 contains a slag collection chamber 11 and a clean water chamber 12, which are located below the cleaning space V1, and the bottom of the cleaning space V1 is connected to the clean water chamber inlet 121. Alternatively, the main structure 10 contains a primary filtration vertical chamber 131, a slag collection chamber 11, and a clean water chamber 12, which are located below the cleaning space V1, and the bottom of the cleaning space V1 is connected to the clean water chamber inlet 121.

[0275] The cleaning equipment 1000 of this invention utilizes a filter device 100 to improve the filtration effect of the washing water, providing cleaner washing water for recycling and improving washing cleanliness. Furthermore, the filter screens in this filter device 100 have a long service life, maintaining a consistently good filtration effect.
