For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0056] The following refers to the attached Figures 1-11Describe the filtering device 100 of the cleaning device 1000 according to an embodiment of the present utility model. The filtering device 100 is used to filter the washing water of the cleaning device 1000 to filter out the residues in the washing water and improve the cleanliness of the washing water. The filtered washing water can be used for circulating washing or in other scenarios. For example, the filtered washing water can be used for irrigation, thereby improving the utilization rate of the washing water.

[0057] The filtering device 100 of the cleaning device 1000 according to an embodiment of the present utility model, refer to Figure 1 , includes: a structural main body 10. The structural main body 10 is the main structure of the filtering device 100, which undertakes the functions of support and protection and provides a sealed filtering environment for the washing water.

[0058] Refer to Figure 2 and Figure 3 , a slag collection chamber 11 is provided inside the structural main body 10. As Figure 6 shown, the slag collection chamber 11 has a slag collection inlet 111 and a slag collection outlet 113. The water flow drives the residues to enter the slag collection chamber 11 from the slag collection inlet 111. After being processed in a certain way, the residues in the water can be gradually separated. The separated residues are stored and accumulated in the slag collection chamber 11, and then the residues can be discharged from the slag collection outlet 113 at an appropriate time.

[0059] In this application, the method of separating the washing water from the residues in the slag collection chamber 11 is not limited. For example, after the water flow drives the residues into the slag collection chamber 11, after a certain period of sedimentation, the residues and water are automatically stratified under the action of gravity. The residues remain at the bottom layer and the washing water remains at the upper layer. At this time, the upper layer of washing water is pumped out, and the residues stored in the slag collection chamber 11 have a reduced water content. Another example is as Figure 6 shown, a slag collection filter screen 20 is provided on the flow path from the slag collection inlet 111 to the slag collection outlet 113 in the slag collection chamber 11. During the flow, the washing water is gradually filtered out by the slag collection filter screen 20, and the remaining residues with a reduced water content are left in the slag collection chamber 11.

[0060] In some embodiments, as Figure 2 shown, the slag collection chamber 11 has a slag collection water outlet 112, as Figure 4As shown, the filtering device 100 further includes a slag collecting filter screen 20. The slag collecting filter screen 20 is located in the slag collecting cavity 11 and is provided at the slag collecting water outlet 112. The slag collecting filter screen 20 is used to filter the water flowing towards the slag collecting water outlet 112 and leave the residues in the slag collecting cavity 11. After being filtered by the slag collecting filter screen 20 in this way, the clean washing water can be led out from the slag collecting water outlet 112. After being led out, the washing water can be recycled or directly discharged. Filtering out the washing water from the residues into the slag collecting cavity 11 here can make the slag collecting cavity 11 only hold the residues. On the one hand, it reduces the volume required for residue storage, enabling more residues to be accumulated in the slag collecting cavity 11. On the other hand, the residues are almost in a solid state and are concentrated in the slag collecting cavity 11, which is more convenient for subsequent processing. For example, when manual slag discharge is required, it is relatively easy to dig out the concentrated residues. Moreover, if the filtered washing water in the slag collecting cavity 11 can be recycled, it can also improve the utilization rate of the washing water and reduce the water consumption of the cleaning device 1000.

[0061] In some embodiments, as Figure 6 shown, the filtering device 100 further includes a slag discharge valve 61, and the slag discharge valve 61 is provided at the slag discharging opening 113 of the slag collecting cavity. By closing the slag discharging opening 113 with the slag discharge valve 61, on the one hand, the position of the slag discharging opening 113 in the slag collecting cavity 11 can be set lower. Even the slag discharging opening 113 can be set at the lowest position of the slag collecting cavity 11. For example, it can be set at the lowest position of the bottom wall surface S1 of the slag collecting cavity 11 or at the lowest position of the side wall surface S2 of the slag collecting cavity 11. In this way, it helps to empty the residues in the slag collecting cavity 11 during slag discharge. On the other hand, the slag discharge valve 61 can close the slag discharging opening 113 when slag discharge is not required, enabling the residues to stand still and be fully liquid-solid separated after entering the slag collecting cavity 11 to filter out more washing water.

[0062] In the solution of this application, the structure of the slag discharge valve 61 is not limited and can be an electromagnetic switch valve or other types of valves.

[0063] In some specific embodiments, as Figure 6 shown, the slag discharge valve 61 is a one-way valve 61a that opens unidirectionally outward from the slag collecting cavity 11, and the one-way valve 61a is controlled to open and close by the pressure difference on both sides. That is to say, the opening and closing of the one-way valve 61a do not require another power component, saving the part cost of the power component. Moreover, the one-way valve 61a itself usually has a relatively simple structure, is convenient for assembly, and can also reduce its occupied volume, facilitating the compact layout of the filtering device 100.

[0064] Specifically, as Figure 8 shown, when the one-way valve 61a is provided at the slag discharging opening 113 of the slag collecting cavity 11, a slag collecting water outlet 112 is also provided in the slag collecting cavity 11, as well as a slag collecting filter screen 20 provided at the slag collecting water outlet 112. In this way, it can reduce the pressure exerted on the one-way valve 61a by the washing water and avoid the situation that the one-way valve 61a is not tightly closed and is accidentally opened.

[0065] In some specific embodiments, asFigure 9 and Figure 10 As shown in Figure 10 , the one-way valve 61a includes a bracket 611 and a valve cover 612. The bracket 611 is provided with a through valve port 6113, and the bracket 611 is installed at the slag collection and discharge port 113. The valve cover 612 is located on the side of the bracket 611 away from the slag collection chamber 11 for covering the valve port 6113, and one end of the valve cover 612 is connected to the bracket 611. In this way, the one-way valve 61a can control the opening and closing of the valve port 6113 through the air pressure intensities acting on both sides of the valve cover 612. Specifically, when the air pressure inside the slag collection chamber 11 is relatively lower than the air pressure outside the slag collection and discharge port 113, the valve cover 612 is sucked at the valve port 6113 to keep it closed. When the air pressure inside the slag collection chamber 11 is relatively higher than the air pressure outside the slag collection and discharge port 113, the valve cover 612 is pushed open to open the valve port 6113. The outside of the slag collection and discharge port 113 here refers to the side that is away from the slag collection chamber 11 among the two sides of the one-way valve 61a. For example, Figure 10 the air pressure in the water collection chamber 14 in Figure 10 is the air pressure outside the slag collection and discharge port 113.

[0066] This one-way valve 61a is integrally in a thin sheet shape, does not occupy too much space, is easy to open and close, and is not easily blocked so that it cannot be closed or opened.

[0067] Specifically, the valve cover 612 is a soft cover. The valve cover 612 is fitted at the valve port 6113 in its natural state, that is, when there is no pressure difference between the inside of the slag collection chamber 11 and the outside of the slag collection and discharge port 113, the valve cover 612 is fitted at the valve port 6113. In this way, when the air pressure inside the slag collection chamber 11 is relatively lower than the air pressure outside the slag collection and discharge port 113, the valve cover 612 can quickly find the valve port 6113 and close the valve port 6113.

[0068] Specifically, as Figure 10 shown in Figure 10 , the upper end of the valve cover 612 is connected to the bracket 611, which is beneficial for the valve cover 612 to droop under the action of gravity in its natural state to be fitted at the valve port 6113.

[0069] Specifically, when the bracket 611 is provided with a through valve port 6113 and the valve cover 612 opens the valve port 6113, the valve port 6113 is in a fully open state, and the area of the valve port 6113 is the flow area of the slag collection and discharge port 113.

[0070] In some specific embodiments, as Figure 10 shown in Figure 10 , the bracket 611 is provided with a socket 6114, and the valve cover 612 is provided with a plug post 6125, and the plug post 6125 is assembled in the socket 6114. Or, the bracket 611 is provided with a plug post 6125, and the valve cover 612 is provided with a socket 6114, and the plug post 6125 is assembled in the socket 6114. This is convenient for assembly and also convenient for disassembly and cleaning.

[0071] Specifically, the jack 6114 is located above the valve port 6113, so that the connection position of the bracket 611 and the valve cover 612 is above the valve port 6113. This is beneficial for the valve cover 612 to be fitted at the valve port 6113 under the action of gravity in the natural state.

[0072] Furthermore, as Figure 10 shown, the valve cover 612 is provided with an insertion post 6125, and the end of the insertion post 6125 is an expansion block 6127 to achieve limiting.

[0073] In some embodiments, as Figure 10 shown, the valve cover 612 is provided with a wire groove 6126, and the wire groove 6126 is located between the insertion post 6125 and the valve port 6113. The wire groove 6126 is a weak stress area 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 and discharge port 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 wire groove 6126, making it easy for the valve cover 612 to open the valve port 6113. Optionally, the wire groove 6126 is a horizontally penetrating groove.

[0074] Specifically, as Figure 10 shown, the side of the bracket 611 facing the valve cover 612 is provided with a positioning rib 6117, and the positioning rib 6117 is located in the wire groove 6126. In this way, when the air pressure inside the slag collection chamber 11 is relatively lower than the air pressure outside the slag collection and discharge port 113 and the valve cover 612 is sucked, through the action of the positioning rib 6117 inserted into the wire groove 6126, the valve cover 612 can be quickly and accurately closed at the valve port 6113.

[0075] Specifically, the valve cover 612 is a soft film, so that not only can the valve cover 612 be opened and closed repeatedly, but it is not easy to break when bent repeatedly, and has a long service life.

[0076] Optionally, the valve cover 612 and the insertion post 6125 are integrally formed, which is convenient for processing and reduces the risk of fracture. Further optionally, the valve cover 612 is a soft film, and the valve cover 612, the insertion post 6125, and the expansion block 6127 are all integrally formed. The insertion post 6215 is a hollow tube, and the insertion post 6215 is open at one end facing the expansion block 6127, which is convenient for extrusion deformation for assembly.

[0077] In some embodiments, as Figure 10 shown, the one-way valve 61a further includes a reinforcing cover plate 613, and the reinforcing cover plate 613 is arranged on the soft film and is disposed opposite to the valve port 6113. This can improve the strength of the valve cover 612 at the valve port 6113, avoid the valve cover 612 being excessively sucked and deformed when the air pressure inside the slag collection chamber 11 is relatively too low compared to the air pressure outside the slag collection and discharge port 113, and avoid the situation where the valve port 6113 cannot be closed due to excessive deformation.

[0078] Specifically, asFigure 10 As shown, a cover groove 6122 is provided on the valve cover 612, and the reinforcing cover plate 613 is fitted in the cover groove 6122. Further, the reinforcing cover plate 613 is interference-fitted in the cover groove 6122, thereby clamping the reinforcing cover plate 613.

[0079] Specifically, an open cover groove 6122 is formed on the side of the valve cover 612 away from the slag collection chamber 11, which is convenient for assembly. Moreover, this surface does not directly face the water flow or residue, reducing the risk of the reinforcing cover plate 613 falling off the valve cover 612. The opening area of the cover groove 6122 is smaller than the corresponding area of the reinforcing cover plate 613, which is convenient for the valve cover 612 to wrap the reinforcing cover plate 613 to prevent it from falling off.

[0080] Optionally, as Figure 10 shown, the valve cover 612 forms a positioning protrusion 6121 on the side facing the slag collection chamber 11. The positioning protrusion 6121 is used to be inserted into the valve port 6113 when the valve cover 612 is closed, thereby improving the firmness and sealing performance when closed.

[0081] Further optionally, the shape of the positioning protrusion 6121 is the same as that of the valve port 6113. For example, both the positioning protrusion 6121 and the valve port 6113 can be semi-circular.

[0082] In some specific embodiments, as Figure 10 shown, the filtering device 100 further includes a first sealing ring 614. The first sealing ring 614 is sleeved on the bracket 611 and is used to achieve a sealed connection between the edge of the bracket 611 and the inner wall surface of the slag collection and discharge port 113. The first sealing ring 614 can also help the bracket 611 to be clamped at the slag collection and discharge port 113 and is not easily knocked down by the pressure difference force and the residue impact force during slag discharge.

[0083] In some embodiments, as Figure 6 shown, the bottom wall surface S1 of the slag collection chamber 11 includes: a diversion bottom surface S11, and the height of the diversion bottom surface S11 gradually decreases in the direction from the slag collection inlet 111 to the slag collection and discharge port 113. In this way, the residue entering the slag collection chamber 11 from the slag collection inlet 111 can be guided by the diversion bottom surface S11 to concentrate towards the slag collection and discharge port 113, improving the residue concentration and facilitating the centralized separation of the washing water and the discharge of the residue.

[0084] Specifically, the inclination angle α of the diversion bottom surface S11 is at least 5°. It can be understood that the residue, especially food residue, has a certain adhesion force. By setting the inclination angle α of the diversion bottom surface S11 to at least 5°, the gravity and water flow impact force of the residue can overcome the adhesion force with the diversion bottom surface S11. In this way, the residue can slide quickly at the bottom of the slag collection chamber 11, reducing the amount of residue hanging on the diversion bottom surface S11.

[0085] In some embodiments, the bottom wall surface S1 of the slag collecting cavity 11 further includes a sunken concave surface S12. One end of the sunken concave surface S12 is connected to the lowest edge of the diversion bottom surface S11, and the height of the sunken concave surface S12 gradually decreases in the direction towards the diversion bottom surface S11. With such a setting, a downward depression is formed at the connection between the sunken concave surface S12 and the diversion bottom surface S11, which can cause the residues to concentrate in the depression, and this depression provides a certain capacity. Forming a depression here instead of forming a depression along the side wall surface S2 of the slag collecting cavity 11 can limitedly avoid the accumulation of residues at the corners, thus facilitating the evacuation of residues.

[0086] Specifically, the slag collecting and discharging opening 113 is located on the side wall surface S2 of the slag collecting cavity 11 and is arranged corresponding to the connection between the sunken concave surface S12 and the diversion bottom surface S11. This helps to discharge the residues concentrated in the sunken concave surface S12 from the slag collecting and discharging opening 113 centrally, reducing the amount of residues remaining in the slag collecting cavity 11.

[0087] Specifically, at least a part of the lower edge of the slag collecting and discharging opening 113 coincides with the intersection line of the sunken concave surface S12 and the side wall surface S2 of the slag collecting cavity 11. This not only facilitates the processing of the slag collecting and discharging opening 113, but also facilitates the smooth discharge of residues along the slag collecting and discharging opening 113, avoiding the situation where steps are formed at the slag collecting and discharging opening 113 and residues are retained.

[0088] More specifically, the intersection line of the sunken concave surface S12 and the side wall surface S2 of the slag collecting cavity 11 includes a downward concave line S1-2, and the downward concave line S1-2 coincides with the lower edge of the slag collecting and discharging opening 113. The lowest point in the middle of the downward concave line S1-2 is also the lowest position in the slag collecting cavity 11, which helps to smoothly evacuate the residues.

[0089] Specifically, the diversion bottom surface S11 is an inclined surface. The highest edge of the diversion bottom surface S11 corresponds to the slag collecting inlet 111, and the lowest edge of the diversion bottom surface S11 corresponds to the slag collecting and discharging opening 113.

[0090] Specifically, the sunken concave surface S12 is an arc surface. Optionally, the downward concave line S1-2 in the intersection line of the sunken concave surface S12 and the side wall surface S2 of the slag collecting cavity 11 is an arc line. Further optionally, the central angle of the downward concave line S1-2 is at least 90 degrees.

[0091] The lateral distance from the highest edge to the lowest edge of the sunken concave surface S12 is much smaller than the lateral distance from the highest edge to the lowest edge of the diversion bottom surface S11.

[0092] In some specific embodiments, the height difference of the diversion bottom surface S11 is at least 5% of the height of the slag collecting cavity 11.

[0093] It is understandable that the slag collection chamber 11 itself has a relatively large space. On the one hand, it is to hold the washing water when the water flow rate is large and provide enough space for the separation of the washing water and the residue. The height difference between the lowest point of the sunken surface S12 and the lowest edge of the diversion bottom surface S11 is set to be at least 5% of the height of the slag collection chamber 11. On the one hand, it can provide enough concentrated space for the residue to be stored, and on the other hand, it forms a shape that is wider at the top and narrower at the bottom, so that the flow rate in the area with more residues above is faster and the amount of residues in the area with lower flow rate below is less. In this way, it is beneficial to empty the residue.

[0094] Optionally, the height difference of the diversion bottom surface S11 can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, etc. of the height of the slag collection chamber 11. Generally, the height difference of the diversion bottom surface S11 does not exceed 20% of the height of the slag collection chamber 11. This is to avoid the overall height of the filtration device 100 being too high due to the excessive height of the slag collection chamber 11.

[0095] In some embodiments, such as Figure 2 and Figure 4 shown, the filtration device 100 further includes: a slag collection spoiler 22, which is arranged in the slag collection chamber 11 and is suitable for agitating the filter residue. Such a setting can promote the flow of water, which is beneficial to avoiding the residue from sinking to the bottom and sticking to the wall, and is beneficial to the concentration and discharge of the residue to the slag collection outlet 113.

[0096] Especially when the residue sinks to the bottom, it is easy to squeeze the water upward, and the bottom residue becomes dry and sticky on the bottom wall surface S1. The setting of the slag collection spoiler 22 can mix the bottom residue with the washing water above, so that the residue can be carried away when the washing water flows, thus helping the residue to concentrate towards the slag collection outlet 113.

[0097] Here, the structural form of the slag collection spoiler 22 is not limited. The slag collection spoiler 22 can be a fixed part in the slag collection chamber 11, or the slag collection spoiler 22 can be a movable part in the slag collection chamber 11.

[0098] In some specific embodiments, the slag collection spoiler 22 is a movable part, and the slag collection spoiler 22 is configured to be driven to move under the flow of water. That is to say, the water flow impacts and pushes the slag collection spoiler 22 to move, and the moving slag collection spoiler 22 can agitate the filter residue. The agitation action of the slag collection spoiler 22 is realized by using the kinetic energy of the water flow, without the need to separately set a driving part for driving, which not only saves the number of parts but also improves energy efficiency.

[0099] In some other specific embodiments, such as Figure 5 and Figure 6As shown, the filter device 100 further includes: a driving assembly 40, which is connected to the slag collection spoiler 22 to drive the slag collection spoiler 22 to move. In other words, the movement of the slag collection spoiler 22 is driven by the driving assembly 40, which not only has high controllability of the action, but also can drive the slag collection spoiler 22 to move when the kinetic energy of the water is insufficient, which is conducive to maintaining continuous stirring of the filter residue and further reducing the phenomenon of the filter residue sinking to the bottom and hanging on the wall.

[0100] In some specific embodiments, the slag collecting spoiler 22 is rotatably disposed in the slag collecting chamber 11, and the driving assembly 40 is used to drive the slag collecting spoiler 22 to rotate. In this way, the structure of the driving assembly 40 is relatively simple, and there is no need to set up an overly complex transmission structure, thereby reducing the occupied space.

[0101] In some specific embodiments, Figure 2 As shown, the slag collecting chamber 11 also has a slag collecting outlet 112, and the filtering device 100 also includes a slag collecting filter 20 disposed at the slag collecting outlet 112. At this time, the slag collecting spoiler 22 is located on the side of the slag collecting filter 20 away from the slag collecting outlet 112. It can be understood that the side of the slag collecting filter 20 facing the slag collecting outlet 112 is the side where the slag collecting filter 20 discharges water, and the side of the slag collecting filter 20 away from the slag collecting outlet 112 is the side where the slag is retained. The slag collecting spoiler 22 is located on the side of the slag collecting filter 20 away from the slag collecting outlet 112, so that the slag collecting spoiler 22 can stir up the residue at the bottom, thereby facilitating the residue to flow to the slag collecting outlet 113, avoiding the residue from accumulating around the slag collecting outlet 112 and blocking the slag collecting filter 20, and avoiding blocking the water flow carrying the residue from flowing to the slag collecting outlet 112.

[0102] When there is a slag collection filter 20 in the slag collection chamber 11, the slag collection spoiler 22 can be arranged on the slag collection filter 20, and the slag collection spoiler 22 can be arranged on the inner wall surface of the slag collection chamber 11, for example, arranged on the bottom wall surface S1 of the slag collection chamber 11 or the side wall surface S2 of the slag collection chamber 11. Or there are multiple slag collection spoilers 22, some of which are arranged on the slag collection filter 20, and some of which are arranged on the inner wall surface of the slag collection chamber 11, so that a variety of structural solutions of the slag collection spoiler 22 can be provided for selection.

[0103] It is understandable that, since the slag collection spoiler 22 is located on the side of the slag collection filter 20 away from the slag collection outlet 112, the slag collection spoiler 22 can also stir the washing water when stirring the residue, and the stirred washing water can wash away the residue on the surface of the slag collection filter 20 when it is flushed onto the slag collection filter 20. In other words, the stirred water flow can wash the surface of the slag collection filter 20 on the side where the residue is retained, reduce the clogging of the slag collection filter 20 by the residue, and improve the filtering effect of the slag collection filter 20. In this way, the frequency of replacement and cleaning of the slag collection filter 20 is reduced.

[0104] In some embodiments, the driving assembly 40 is connected to the slag collecting filter screen 20 to drive the slag collecting filter screen 20 to rotate. The driving assembly 40 is used to provide power to drive the slag collecting filter screen 20 to rotate at a high speed, and a centrifugal force is generated under the high-speed rotation of the slag collecting filter screen 20, so that the residues mixed in the sewage and the residues attached to the slag collecting filter screen 20 can be separated from the slag collecting filter screen 20 under the action of the centrifugal force, which is beneficial to removing the residues blocking the mesh holes of the slag collecting filter screen 20.

[0105] It can be understood that a conventional filter screen is prone to being blocked after being used for a period of time. To increase the filtering capacity of the filter screen, the general method is to increase the filter screen area, but this will increase the cost of the filter screen and the space occupied by the filter screen. Another method is to take out the filter screen every time the filtering effect decreases, and use a scraper to clean the residues blocking the mesh holes. However, the scraper cleaning will squeeze the filter screen, and the extrusion of the filter screen will affect the performance and service life of the filter screen. Moreover, if the filter screen is often squeezed by the scraper, the toughness of the filter screen will decrease, and when there is water flow through the filter screen during use, it is also easy to be squeezed and deformed by the water flow, clamping off the residues blocking the mesh holes, and the broken residues flow to the slag collecting water outlet along with the water flow, forming secondary pollution and affecting the cleaning effect.

[0106] In the present application, when the driving assembly 40 is provided to drive the slag collecting filter screen 20 to rotate, the residues blocking the slag collecting filter screen 20 can be thrown away, and the filtering effect of the slag collecting filter screen 20 can be maintained. Moreover, after there is no extrusion by the scraper, the service life of the slag collecting filter screen 20 can be prolonged, the cleaning frequency of the slag collecting filter screen 20 can be reduced, the probability of subsequent secondary pollution of the slag collecting filter screen 20 can be reduced, and the cleaning effect of the reused washing water can be improved.

[0107] In some embodiments, when the filtering device 100 further includes a rotatable slag collecting filter screen 20, as Figure 4 shown, the slag collecting flow disturbing member 22 is arranged on the slag collecting filter screen 20, so that the slag collecting filter screen 20 and the slag collecting flow disturbing member 22 can act simultaneously to achieve linkage. In this way, the structure can be simplified and the compactness can be improved.

[0108] For example, when the slag collecting flow disturbing member 22 is driven to rotate by water flow, while the water flow pushes the slag collecting flow disturbing member 22 to rotate, it also drives the slag collecting filter screen 20 to rotate. The slag collecting filter screen 20 does not need to be provided with a separate driving member for driving, which not only saves the number of parts but also improves energy efficiency. Another example is that when there is a driving assembly 40 connected to the slag collecting flow disturbing member 22 to drive the slag collecting flow disturbing member 22 to move, the slag collecting filter screen 20 can be driven to rotate at the same time.

[0109] Specifically, when the slag collecting and flow disturbing member 22 is provided on the slag collecting filter screen 20, the slag collecting and flow disturbing member 22 is disposed adjacent to the bottom wall surface S1 of the slag collecting chamber 11. In this way, the slag collecting and flow disturbing member 22 can achieve dual functions. On the one hand, it can stir up the residues settled at the bottom, avoiding the adhesion of residues, enabling the residues to be mixed with the washing water and flow downward under the drive of the water flow. On the other hand, even when the water level is relatively low, the slag collecting and flow disturbing member 22 near the bottom can also stir up the water flow, causing the water flow to flow to the surface of the slag collecting filter screen 20 under the drive of the slag collecting and flow disturbing member 22, washing away the surface residues, reducing the blockage amount of residues on the slag collecting filter screen 20, and prolonging the service life.

[0110] In some embodiments, as Figure 7 shown, the slag collecting filter screen 20 includes: a first filter cylinder 21, the first filter cylinder 21 covers the slag collecting water outlet 112, and a first mesh hole 211 is provided on the first filter cylinder 21. The setting of the first filter cylinder 21 here enables the slag collecting filter screen 20 to obtain a larger filtering area, and the water flow can flow to the slag collecting water outlet 112 from 360-degree directions, and all the water flows flowing to the slag collecting water outlet 112 have to pass through the filtration of the first filter cylinder 21. The structure of the first filter cylinder 21 is simple and the processing cost is low.

[0111] It should be noted that the maximum passing particle size of the slag collecting filter screen 20 can be limited by the size of the first mesh hole 211 on the first filter cylinder 21. For example, when the width of the first mesh hole 211 is set at 0.1 mm, the first filter cylinder 21 can leave the residues with a particle size exceeding 0.1 mm in the slag collecting chamber 11, while the residues with a particle size less than 0.1 mm may flow to the slag collecting water outlet 112 along with the washing water flow. Alternatively, at least one layer of filter cloth can be provided on the surface of the first filter cylinder 21. The first filter cylinder 21 is a rigid member for supporting the filter cloth, and the maximum passing particle size of the slag collecting filter screen 20 is limited by the mesh size of the filter cloth.

[0112] As Figure 4 shown, the slag collecting and flow disturbing member 22 is connected to the outer peripheral surface of the first filter cylinder 21 to guide the water flow to flow on the outer peripheral surface of the first filter cylinder 21. When the slag collecting filter screen 20 is rotatable, the structure of the first filter cylinder 21 enables the radial distances between various parts on the first filter cylinder 21 and the slag collecting water outlet 112 to be substantially the same, obtaining a consistent centrifugal force, which is beneficial to evenly throwing out the residues on all surfaces. Optionally, the first filter cylinder 21 is a cylinder, and when the driving assembly 40 operates, the first filter cylinder 21 rotates around the center of the slag collecting water outlet 112.

[0113] The slag collecting and flow disturbing member 22 guides the water flow to flow on the outer peripheral surface of the first filter cylinder 21. The action of the slag collecting and flow disturbing member 22 lengthens the flow path of the water flow along the outer peripheral surface of the first filter cylinder 21, so that more residues can be impacted, and the slag collecting and flow disturbing member 22 can guide the water flow to impact the residues on the first filter cylinder 21 tangentially, making it easier for the residues to be knocked off and separated from the first filter cylinder 21. Thus, the slag removal and anti-blocking ability of the first filter cylinder 21 is improved.

[0114] In some specific embodiments, Figure 4 As shown, the slag spoiler 22 includes a plurality of slag spoilers 221 spaced apart along the circumferential direction, and the slag spoilers 221 are arranged to extend obliquely relative to the rotation axis of the slag filter 20. In this way, the water flow on the upper surface of the slag spoilers 221 can continue to flow upward along the slag spoilers 221. After all the slag spoilers 221 rotate, the water flow forms an upward vortex on the surface of the slag filter 20, so that the vortex impact force is large, and each stream of water flows more persistently under the influence of each other, thereby enhancing the impact force of the water flow, extending the impact distance of the water flow, and improving the ability to remove the filter residue.

[0115] Specifically, Figure 4 As shown, the upper surface f1 of the slag collection spoiler 221 is an arc-shaped surface, and the upper end of the slag collection spoiler 221 gradually approaches the horizontal plane, so that the water flow can be guided to flow in a circumferential rotation. In this way, each stream of water pushes the water flow on one side in the circumferential direction, and each stream of water is pushed by the water flow on the other side in the circumferential direction. All water flows push each other, which is conducive to maintaining the swirling power of the water flow and prolonging the rotation flow time, thereby enhancing the impact force of the water flow on the slag collection filter screen 20 and improving the cleaning ability of the filter residue.

[0116] Furthermore, if Figure 6 As shown, the slag collection spoiler 221 forms a circle at the lower end of the slag collection filter screen 20, rather than multiple circles. In this way, when the water flow is directed upward by the slag collection spoiler 221, it will not encounter another circle of spoilers to cause flow obstruction.

[0117] In some specific embodiments, Figure 6 and Figure 7 As shown, the slag collection filter screen 20 is arranged vertically, and a slag collection spoiler 22 is arranged at the bottom of the slag collection filter screen 20. In this way, the slag collection spoiler 22 can prevent the residue from sinking to the bottom of the slag collection chamber 11, and also facilitate the slag collection filter screen 20 to be tall and thin as a whole, reduce the resistance to water flow, and reduce the occupation of the slag collection space.

[0118] After such configuration, when the slag filter 20 is driven to rotate by the driving assembly 40, the driving assembly 40 can be set below or above the slag collecting chamber 11, and can be avoided as much as possible from being set on the side wall surface S2 of the slag collecting chamber 11 to avoid the overall occupied area being too large to be used in the kitchen.

[0119] Specifically, Figure 7 As shown, the slag collection outlet 112 is provided on the bottom wall surface S1 of the slag collection chamber 11, and the slag collection filter 20 is vertically provided and covers the slag collection outlet 112. The slag collection filter 20 is higher than the bottom wall surface S1 of the slag collection chamber 11 at least at the mesh point. In this way, on the one hand, the water flow characteristics are utilized to allow the filtered water to be quickly discharged from the slag collection outlet 112, and on the other hand, the residue is prevented from accumulating and blocking the mesh points of the slag collection filter 20.

[0120] In some specific embodiments, such as Figure 6 and Figure 8 shown, the structural body 10 includes a retaining platform 114 provided on the bottom wall surface S1 of the slag collection chamber 11. The retaining platform 114 is arranged around the slag collection water outlet 112, and the slag collection filter screen 20 is provided on the retaining platform 114, so that the slag collection filter screen 20 is higher than the bottom wall surface S1 of the slag collection chamber 11.

[0121] The retaining platform 114 raises the slag collection filter screen 20, so that the lower edge of the slag collection filter screen 20 is located on the retaining platform 114, and the gap between the two is at a relatively high position, avoiding a large amount of bottom residues from flowing to the slag collection water outlet 112 through this gap.

[0122] In some embodiments, such as Figure 11 shown, a slag collection cleaning port 171 communicating with the slag collection chamber 11 is formed on the structural body 10. As Figure 7 and Figure 8 shown, the filtering device 100 further includes a slag collection cover 62, and the slag collection cover 62 is detachably installed at the slag collection cleaning port 171. In this way, when performing maintenance or cleaning, it is convenient to open the slag collection cover 62 and perform operations such as observation, cleaning, and maintenance from the slag collection cleaning port 171.

[0123] Here, the slag collection cleaning port 171 is located on the top wall of the slag collection chamber 11, so the probability of water leakage is relatively low. Of course, in some solutions, the slag collection cleaning port 171 may also be located on the side wall surface S2 of the slag collection chamber 11.

[0124] Specifically, the projection of the slag collection filter screen 20 on the plane where the slag collection cleaning port 171 is located is completely within the slag collection cleaning port 171, and the slag collection filter screen 20 is detachably arranged in the slag collection chamber 11. In this way, it is convenient to remove and take out the slag collection filter screen 20 from the slag collection cleaning port 171, improving the convenience of maintenance and cleaning.

[0125] Furthermore, as Figure 11 shown, a first snap structure 115 is provided on the edge of the slag collection cover 62 to cooperate with 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 open by water flow, and when cleaning, the slag collection cover 62 is screwed out.

[0126] In some embodiments, such as Figure 7 and Figure 8 shown, the slag collection filter screen 20 is rotatably connected to the slag collection cover 62 through a first bearing 64. In this way, while setting the slag collection cover 62, the slag collection cover 62 is used to support the rotation of the slag collection filter screen 20, which can improve the rotation stability and avoid damage caused by the swinging of the slag collection filter screen 20 during rotation.

[0127] In some embodiments, such as Figure 7As shown, the slag collection cleaning port 171 is disposed opposite to the slag collection water outlet 112, and the slag collection filter screen 20 is provided at the slag collection water outlet 112, facilitating the direct removal of the slag collection filter screen 20.

[0128] Specifically, the slag collection filter screen 20 is detachably connected to the driving assembly 40. In this way, after the slag collection cover 62 is opened, the slag collection filter screen 20 can be detached from the driving assembly 40. After the maintenance is completed, the slag collection filter screen 20 is reinstalled on the driving assembly 40.

[0129] Specifically, as Figure 7 and Figure 8 shown, the driving assembly 40 includes a driving member 41 and a first rotating shaft 42. The first rotating shaft 42 is vertically arranged. One end of the first rotating shaft 42 is power-connected to the driving member 41, and the other end is connected to the slag collection filter screen 20. It is convenient to set the connection position of the first rotating shaft 42 and the slag collection filter screen 20 according to the position of the rotation center of the slag collection filter screen 20.

[0130] Specifically, one end of the first rotating shaft 42 extends into the slag collection chamber 11 through the slag collection water outlet 112, and the first rotating shaft 42 is connected to the slag collection filter screen 20. In this way, it is convenient for the slag collection filter screen 20 to rotate around the center of the slag collection water outlet 112.

[0131] Furthermore, as Figure 7 and Figure 4 shown, the slag collection filter screen 20 further includes a first top cover 23 connected to the top of the first filter cylinder 21. The top cover 23 is sleeved outside the first rotating shaft 42, and a first bearing 64 is fitted between the top cover 23 and the first rotating shaft 42. In this way, the torsional resistance performance of the slag collection filter screen 20 can be improved, and the connection reliability is high, and the rotation is more stable.

[0132] In some embodiments, as Figure 2 and Figure 3 shown, the structural main body 10 further includes: a purified water chamber 12. The purified water chamber 12 has a purified chamber inlet 121, a purified water outlet 122, and a waste outlet 123. The waste outlet 123 communicates with the slag collection inlet 111. The filtering device 100 further includes: a purified water filter screen 30 provided on the purified water outlet 122.

[0133] That is to say, in the flow direction of the residue, the purified water chamber 12 is located upstream of the slag collection chamber 11. The washing water containing residues enters the purified water chamber 12 from the purified chamber inlet 121. After being filtered by the purified water filter screen 30, the filtered washing water is discharged from the purified water outlet 122, and the remaining residues containing a certain amount of moisture are discharged from the waste outlet 123 to the slag collection chamber 11 and further separated in the slag collection chamber 11, and the residues are concentrated at the slag collection outlet 113 and then discharged. In this way, through the prior filtration of the purified water filter screen 30, the water content in the residues discharged to the slag collection chamber 11 is reduced, facilitating the centralized treatment of the residues.

[0134] In some embodiments, the filter device 100 further includes: a clean water flow spoiler (not shown), which is disposed in the clean water chamber 12, and is located on the side of the clean water filter 30 away from the clean water outlet 122, and is suitable for stirring the water flow. That is, in the flow direction of the clean water, the clean water flow spoiler is located on the upstream side of the clean water filter 30.

[0135] Specifically, the water purification spoiler can stir the flow of water in the water purification chamber 12, which can effectively prevent the accumulation of residues in the water purification chamber 12. At the same time, the stirred water flow can wash the surface of the upstream side of the water purification filter 30 to prevent the residues from clogging the water purification filter 30, thereby improving the filtering effect of the filtering device 100. The water flow stirred by the water purification spoiler can better drive the residues into the residue collection chamber 11 through the waste outlet 123 to facilitate centralized treatment of the residues.

[0136] like Figure 11 As shown, the waste outlet 123 is higher than the bottom wall surface S6 of the water purification chamber 12, so that the water flow can be prevented from flowing into the waste outlet 123 without being filtered when the water flow is too fast. Moreover, after such arrangement, the waste outlet 123 is higher than the water purification outlet 122, so that the water flow at the bottom of the water purification chamber 12 is prevented from not flowing to the water purification outlet 122. Thus, the water output of the water purification chamber 12 can be increased.

[0137] Furthermore, the slag collecting inlet 111 is higher than the bottom wall surface S1 of the slag collecting chamber 11 , which can prevent the residue in the slag collecting chamber 11 from being directly impacted by the water flow and returning to the water purification chamber 12 .

[0138] The provision of the water purification spoiler not only facilitates the automatic discharge of residues from the filter device 100, and can effectively prevent residues from clogging and accumulating in the water purification chamber 12, but can also effectively clean the residues adhering to the surface of the upstream side of the water purification screen 30, prevent the water purification screen 30 from being blocked, and maintain the filtration efficiency of the water purification screen 30. At the same time, the water purification spoiler stirs the flow of water on the upstream side, and can further improve the filtering effect of the residues.

[0139] When there is a water purification screen 30 in the water purification chamber 12, the water purification spoiler can be arranged on the water purification screen 30, and the water purification spoiler can be arranged on the inner wall surface of the water purification chamber 12, for example, arranged on the bottom wall surface S6 of the water purification chamber 12 or the side wall surface S5 of the water purification chamber 12. Or there are multiple water purification spoilers, some of which are arranged on the water purification screen 30, and some of which are arranged on the inner wall surface of the water purification chamber 12, so that a variety of water purification spoiler structural solutions can be provided for selection.

[0140] The water purification spoiler can also effectively prevent blockage in the water purification chamber 12. When assembling the filter device 100, it is only necessary to ensure that the water purification spoiler is located between the upstream side of the water purification filter 30 and the side wall surface S5 of the water purification chamber 12. Such a position can ensure that the water purification spoiler can stir the water flow on the upstream side of the water purification filter 30.

[0141] When the purified water turbulence member protrudes from the surface on the upstream side of the purified water filter screen 30, the purified water turbulence member can more directly agitate the fluid and residual residues on the upstream side, making it easier for them to enter the slag collection chamber 11 through the waste outlet 123. The protruding design increases the contact area between the purified water turbulence member and the fluid, thereby improving the agitation effect.

[0142] When the purified water turbulence member protrudes from the inner wall surface of the purified water chamber 12, after being reasonably arranged, the purified water turbulence member can not only agitate the fluid and residues on the upstream side, but also may have a certain influence on the fluid flow in the purified water chamber 12, guiding more residues to move towards the waste outlet 123, thereby improving the slag discharge efficiency.

[0143] When the purified water turbulence member is located between the upstream side of the purified water filter screen 30 and the inner wall surface of the purified water chamber 12, the purified water turbulence member can be reasonably planned according to the actual size of the filtration device 100, with higher flexibility. For example, the filtration device 100 can optimize the purified water turbulence member by adjusting its position, angle or movement mode, and according to different cleaning requirements and usage scenarios, so as to achieve the best agitation and slag discharge effects.

[0144] Specifically, as Figure 3 shown, the distribution positions of the purified water chamber inlet 121 and the waste outlet 123 will affect the separation effect. Spacing the purified water chamber inlet 121 and the waste outlet 123 circumferentially in the purified water chamber 12 can prevent the separated residues from mixing into the water again, and can ensure that the residues are more evenly distributed in the purified water chamber 12 when entering the purified water chamber 12, reducing the situation of excessive or insufficient local distribution, thereby improving the filtration efficiency and filtration effect.

[0145] In some specific embodiments, the purified water turbulence member is a movable member, and the purified water turbulence member is configured to be driven to move under the flow of water. That is to say, the water flow impacts and pushes the purified water turbulence member to move, and the movable purified water turbulence member can agitate the filter residues. The agitation action of the purified water turbulence member is realized by using the kinetic energy of the water flow, without the need to separately set a driving member to drive, which not only saves the number of parts but also improves energy efficiency.

[0146] In some other specific embodiments, the filtration device 100 further includes: a driving assembly 40, and the driving assembly 40 is connected to the purified water turbulence member to drive the purified water turbulence member to move. Not only is the controllability of the action high, but also when the kinetic energy of the water flow is insufficient, the driving assembly 40 can drive the purified water turbulence member to move, which is beneficial to maintaining continuous agitation of the filter residues and further reducing the phenomenon of filter residues sinking to the bottom and sticking to the wall.

[0147] In some specific embodiments, the purified water turbulence member is rotatably arranged in the purified water chamber 12, and the driving assembly 40 is used to drive the purified water turbulence member to rotate, so that the structure of the driving assembly 40 is relatively simple.

[0148] In some embodiments, such as Figure 7 shown, the driving assembly 40 is connected to the water purification filter screen 30 to drive the water purification filter screen 30 to rotate. The driving assembly 40 is used to provide power to drive the water purification filter screen 30 to rotate at a high speed, and a centrifugal force is generated under the high-speed rotation of the water purification filter screen 30, so that the residues mixed in the sewage and the residues attached to the water purification filter screen 30 can be separated from the water purification filter screen 30 under the action of the centrifugal force, which is not only beneficial to the flow of the residues towards the waste outlet 123, but also beneficial to removing the residues blocking the mesh holes of the water purification filter screen 30.

[0149] When the driving assembly 40 is set to drive the water purification filter screen 30 to rotate, the residues blocked on the water purification filter screen 30 can be thrown away, maintaining the filtering effect of the water purification filter screen 30. Moreover, without the extrusion of the scraper, the service life of the water purification filter screen 30 can be extended, the cleaning frequency of the water purification filter screen 30 can be reduced, the probability of subsequent secondary pollution of the water purification filter screen 30 can be reduced, and the cleaning effect of the reused washing water can be improved.

[0150] In some embodiments, when the filtering device 100 further includes a rotatable water purification filter screen 30, the water purification turbulence member is arranged on the water purification filter screen 30, so that the water purification filter screen 30 and the water purification turbulence member can act simultaneously to achieve linkage. In this way, the structure can be simplified and the compactness can be improved.

[0151] Specifically, when the water purification turbulence member is arranged on the water purification filter screen 30, the water purification turbulence member is arranged adjacent to the bottom wall surface S6 of the water purification cavity 12. In this way, the water purification turbulence member can achieve dual functions. On the one hand, it can stir up the residues sinking to the bottom, avoid the adhesion of the residues, enable the residues to be mixed with the washing water and flow circumferentially under the drive of the water flow, so as to flow to the waste outlet 123. On the other hand, when the water level is low, the water purification turbulence member near the bottom can stir up the water flow, so that the water flow can flow to the surface of the water purification filter screen 30 under the drive of the water purification turbulence member, wash away the surface residues, reduce the blockage amount of the residues on the water purification filter screen 30, and extend the service life.

[0152] In some embodiments, such as Figure 7 shown, the water purification filter screen 30 includes: a second filter cylinder 31, the second filter cylinder 31 covers the water purification outlet 122, and the second filter cylinder 31 is provided with second mesh holes 311. The setting of the second filter cylinder 31 here enables the water purification filter screen 30 to obtain a larger filtering area, the water flow can flow towards the water purification outlet 122 from a 360-degree direction, and all the water flows towards the water purification outlet 122 have to pass through the filtration of the second filter cylinder 31. The structure of the second filter cylinder 31 is simple and the processing cost is low.

[0153] It should be noted that the maximum passing particle size of the water purification filter screen 30 can be limited by the size of the second mesh holes 311 on the second filter cylinder 31. For example, when the width of the second mesh holes 311 is set at 0.3 mm, the second filter cylinder 31 can leave residues with a particle size exceeding 0.3 mm in the water purification cavity 12 and flow along the water flow to the waste outlet 123. Residues with a particle size less than 0.3 mm may flow along the washing water to the water purification outlet 122. Alternatively, at least one layer of filter cloth can be arranged on the surface of the second filter cylinder 31. The second filter cylinder 31 is a rigid member for supporting the filter cloth, and the maximum passing particle size of the water purification filter screen 30 is limited by the mesh size of the filter cloth.

[0154] The water purification flow disturbing member is connected to the outer peripheral surface of the second filter cylinder 31 to guide the water flow to flow on the outer peripheral surface of the second filter cylinder 31. When the water purification filter screen 30 is rotatable, the structure of the second filter cylinder 31 is adopted to make the radial distances from various parts on the second filter cylinder 31 to the water purification outlet 122 substantially the same, so as to obtain a consistent centrifugal force. Optionally, when the driving assembly 40 operates, the second filter cylinder 31 rotates around the center of the water purification outlet 122.

[0155] The water purification flow disturbing member guides the water flow to flow on the outer peripheral surface of the second filter cylinder 31. The function of the water purification flow disturbing member is to lengthen the flow path of the water flow along the outer peripheral surface of the second filter cylinder 31, so that more residues can be impacted. Moreover, the water purification flow disturbing member can guide the water flow to impact the residues on the second filter cylinder 31 tangentially, making the residues easier to be knocked off and separated from the second filter cylinder 31. Thus, the slag removal and anti-blocking ability of the second filter cylinder 31 is improved.

[0156] In some specific embodiments, the water purification flow disturbing member includes a plurality of water purification flow disturbing vanes that are circumferentially spaced apart. The water purification flow disturbing vanes are inclined and extended relative to the rotation axis of the water purification filter screen 30. In this way, the water flow on the upper surface of the water purification flow disturbing vane can continue to flow upward along the water purification flow disturbing vane. After all the water purification flow disturbing vanes rotate, the water flow forms an upward swirling flow on the surface of the water purification filter screen 30. Such a swirling flow has a large impact force, and each water flow flows more persistently under the mutual influence, enhancing the water flow impact force, extending the water flow impact distance, and improving the filter residue removal ability.

[0157] Optionally, the upper surface of the water purification flow disturbing vane is an arc surface, and the upper end of the water purification flow disturbing vane gradually approaches the horizontal plane, so as to guide the water flow to rotate circumferentially. In this way, each water flow presses and pushes the water flow on one side circumferentially, and each water flow is pressed and pushed by the water flow on the other side circumferentially. All the water flows press and push each other, which is beneficial to the water flow to maintain the swirling power and extend the rotation flow time, thereby enhancing the impact force of the water flow on the water purification filter screen 30 and improving the filter residue cleaning ability.

[0158] Furthermore, the water purification flow disturbing vanes form a circle at the lower end of the water purification filter screen 30 instead of being arranged in multiple circles. In this way, when the water flow is upwardly deflected by the water purification flow disturbing vanes, it will not encounter another circle of flow disturbing vanes and cause the flow to be blocked.

[0159] In some specific embodiments, the water purification filter screen 30 is vertically arranged, and a water purification turbulence generating member is arranged at the bottom of the water purification filter screen 30. In this way, while the water purification turbulence generating member can prevent residues from settling at the bottom of the water purification cavity 12, it also facilitates the overall slender shape of the water purification filter screen 30, reduces the resistance to water flow, and reduces the occupation of the slag collection space.

[0160] In some embodiments, as Figure 11 shown, a net cavity cleaning port 172 communicating with the water purification cavity 12 is formed on the structural main body 10. As Figure 7 and Figure 8 shown, the filtering device 100 further includes a net cavity cover 63, and the net cavity cover 63 is detachably installed at the net cavity cleaning port 172. In this way, when performing maintenance or cleaning, it is convenient to open the net cavity cover 63 and perform operations such as observation, cleaning, and maintenance from the net cavity cleaning port 172.

[0161] Here, the net cavity cleaning port 172 is located on the top wall of the water purification cavity 12, so the probability of water leakage is relatively low. Of course, in some solutions, the net cavity cleaning port 172 may also be located on the side wall surface S5 of the water purification cavity 12.

[0162] Specifically, the projection of the water purification filter screen 30 on the plane where the net cavity cleaning port 172 is located is completely within the net cavity cleaning port 172, and the water purification filter screen 30 is detachably arranged in the water purification cavity 12. In this way, it is convenient to remove and take out the water purification filter screen 30 from the net cavity cleaning port 172, improving the convenience of maintenance and cleaning.

[0163] Furthermore, as Figure 11 shown, a second snap structure 125 is provided on the edge of the net cavity cover 63 to cooperate with the inner edge of the net cavity cleaning port 172, so that the net cavity cover 63 can be rotatably connected to the net cavity cleaning port 172. When in use, the net cavity cover 63 is screwed on to prevent it from being washed open by water flow, and when cleaning, the net cavity cover 63 is screwed out.

[0164] In some embodiments, as Figure 7 and Figure 8 shown, the water purification filter screen 30 is rotatably connected to the net cavity cover 63 through a second bearing 68. In this way, while setting the net cavity cover 63, the net cavity cover 63 is used to support the rotation of the water purification filter screen 30, which can improve the rotation stability and avoid damage caused by the swinging of the water purification filter screen 30 during rotation.

[0165] In some embodiments, as Figure 7 shown, the net cavity cleaning port 172 is oppositely arranged with the water purification outlet 122, and the water purification filter screen 30 is arranged at the water purification outlet 122, which is convenient for directly taking out the water purification filter screen 30.

[0166] Specifically, the water purification filter 30 is detachably connected to the driving assembly 40, so that when the clean chamber cover 63 is opened, the water purification filter 30 can be removed from the driving assembly 40. After the maintenance is completed, the water purification filter 30 is installed back on the driving assembly 40.

[0167] Specifically, Figure 7 and Figure 8 As shown, the driving assembly 40 includes a driving member 41 and a second rotating shaft 43, the second rotating shaft 43 is vertically arranged, one end of the second rotating shaft 43 is connected to the driving member 41, and the other end is connected to the water purification filter 30. In this way, it is convenient to set the connection position of the second rotating shaft 43 and the water purification filter 30 according to the position of the rotation center of the water purification filter 30.

[0168] Specifically, one end of the second rotating shaft 43 extends into the water purification chamber 12 through the water purification outlet 122 , and the second rotating shaft 43 is connected to the water purification filter 30 , so that the water purification filter 30 can rotate around the center of the water purification outlet 122 .

[0169] Furthermore, if Figure 7 and Figure 4 As shown, the water purification filter 30 also includes a second top cover 33 connected to the top of the second filter cartridge 31, the top cover 33 is covered with a second rotating shaft 43, and the second bearing 68 is fitted between the top cover 33 and the second rotating shaft 43, so that the torsional performance of the water purification filter 30 can be improved, and the connection reliability is high, and the rotation is more stable.

[0170] In some embodiments, the water purification spoiler is linked with the slag collection spoiler 22. In this way, when one of them is driven to move, the other also moves synchronously, thus increasing the activity frequency of the two and enhancing the disturbance effect.

[0171] For example, the water flow in the water purification chamber 12 is large, and the water purification spoiler can move under the impact of the water flow, and at the same time drive the slag collection spoiler 22 to move. For another example, the driving component 40 drives one of the activities and drives the other activity at the same time.

[0172] In some specific embodiments, Figure 7 As shown, both the slag collection filter 20 and the water purification filter 30 are rotatably arranged on the structural body 10, and the slag collection filter 20 and the water purification filter 30 are arranged in linkage. The driving assembly 40 drives one of them to rotate and drives the other to rotate at the same time, so that one set of driving assemblies 40 can be saved and the arrangement of parts is convenient.

[0173] Furthermore, the driving assembly 40 is connected to at least one of the slag collection filter 20 and the water purification filter 30 to drive the slag collection filter 20 and the water purification filter 30 to rotate simultaneously. In other words, the slag collection filter 20 and the water purification filter 30, the water purification spoiler and the slag collection spoiler 22 are all linked, and only one set of driving assemblies 40 can complete the activities of the four, reducing the number of parts and improving the compactness of the parts.

[0174] In some specific embodiments, such as Figure 7 and Figure 5 shown, the driving assembly 40 includes: a driving member 41, a first rotating shaft 42 and a second rotating shaft 43. One end of the first rotating shaft 42 extends into the slag collecting chamber 11 and is connected to the slag collecting filter screen 20. The other end of the first rotating shaft 42 is power-connected to the driving member 41. One end of the second rotating shaft 43 extends into the purified water chamber 12 and is connected to the purified water filter screen 30. The other end of the second rotating shaft 43 is power-connected to the driving member 41. After the two shafts are arranged, they are connected to the two filter screens. The structure is simple and there is no need to provide too much space.

[0175] In some embodiments, such as Figure 1 shown, the filtering device 100 further includes: a flow channel plate 50, and the flow channel plate 50 is arranged at the bottom of the structural body 10. The driving member 41 is installed on the flow channel plate 50, which reduces the processing difficulty and sealing difficulty of the structural body 10.

[0176] Specifically, as Figure 7 and Figure 8 shown, the first rotating shaft 42 is arranged vertically, and the upper end of the first rotating shaft 42 extends into the slag collecting chamber 11 through the slag collecting water outlet 112. The second rotating shaft 43 is arranged vertically, and the upper end of the second rotating shaft 43 extends into the purified water chamber 12 through the purified water outlet 122. This facilitates the rotation of the slag collecting filter screen 20 around the center of the slag collecting water outlet 112 and the rotation of the purified water filter screen 30 around the center of the purified water outlet 122.

[0177] In some specific embodiments, such as Figure 7 and Figure 8 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 driving assembly 40 further includes: a first gear 44 installed on the first rotating shaft 42 and a second gear 45 installed on the second rotating shaft 43. The first gear 44 and the second gear 45 are meshed with each other, and the driving member 41 is matched with one of the first gear 44 and the second gear 45. With this setting, the gear set for linkage can be arranged in the flat gear groove 52, reducing the overall height dimension. In addition, with gear transmission, it is also convenient to adjust the speed ratio according to the tooth number ratio, which helps the slag collecting filter screen 20 and the purified water filter screen 30 to obtain appropriate rotation speeds respectively.

[0178] In some embodiments, such as Figure 7 and Figure 8 shown, the gear groove 52 is arranged to open downward, and the filtering device 100 further includes a gear cover 66 fitted to the bottom of the flow channel plate 50. This facilitates assembly, maintenance and inspection.

[0179] In some embodiments, such as Figure 7 and Figure 6As shown, the driving member 41 is a driving motor 41a which is vertically installed on the flow channel plate 50. The driving motor 41a is located on the horizontal side of the structural body 10. A motor shaft 411 is provided at the lower end of the driving motor 41a and extends into the gear groove 52. The driving assembly 40 further includes a third gear 46. The third gear 46 is installed on the motor shaft 411, and the third gear 46 meshes with the first gear 44 or the second gear 45. In this way, on the one hand, speed reduction and torque increase can be achieved, and on the other hand, the driving member 41 can be integrated on the horizontal side of the structural body 10, avoiding the situation that the entire filtering device 100 is too high.

[0180] In some embodiments, as Figures 1-9 shown, the filtering device 100 further includes a circulation pump 65. The inlet end 651 of the circulation pump 65 is communicated with the slag collection water outlet 112. When the circulation pump 65 works, it is used to suck the water collected at the slag collection water outlet 112, and make the slag collection chamber 11 in a negative pressure state. In this way, the residue can be kept stationary in the negative pressure state of the slag collection chamber 11, avoiding the situation that the slag inlet 111 has poor slag inlet due to too high air pressure in the slag collection chamber 11.

[0181] In some embodiments, when the filtering device 100 includes a circulation pump 65, the inlet end 651 of the circulation pump 65 is also communicated with the purified water outlet 122. When the circulation pump 65 works, it is used to suck the water collected at the purified water outlet 122 to complete the circulating flow and use of the washing water.

[0182] Specifically, as Figure 8 shown, when the circulation pump 65 works, the slag discharge valve 61 closes the slag collection and discharge port 113, and when the circulation pump 65 stops working, the slag discharge valve 61 opens the slag collection and discharge port 113. In this way, the circulation pump 65 and the slag discharge valve 61 cooperate with each other to realize automatic slag collection and discharge.

[0183] Specifically, the slag discharge valve 61 is a one-way valve 61a that opens unidirectionally outward from the slag collection chamber 11, and the one-way valve 61a is controlled to open and close by the pressure difference on both sides. At this time, the circulation pump 65 is used to control the air pressure inside.

[0184] In some embodiments, as Figure 7 and Figure 8 shown, a purified water flow channel 51 is provided in the flow channel plate 50. The purified water flow channel 51 is communicated with the slag collection water outlet 112 and the purified water outlet 122. Here, a single purified water flow channel 51 is simultaneously connected to the slag collection water outlet 112 and the purified water outlet 122, reducing the number of flow channels, which is beneficial to simplifying the internal structure of the flow channel plate 50. The inlet end 651 of the circulation pump 65 is communicated with the purified water flow channel 51. In this way, the washing water obtained after purification can flow through the purified water flow channel 51 to the circulation pump 65 and be recycled.

[0185] In some embodiments, as Figure 7 and Figure 8As shown, the filtering device 100 further includes a backwashing member 55. The backwashing member 55 is disposed in the purified water chamber 12. A backwashing flow channel 551 is provided in the backwashing member 55. Spray holes 552 communicating with the backwashing flow channel 551 and facing the purified water filter screen 30 are provided on the backwashing member 55. The water sprayed from the backwashing member 55 through the spray holes 552 is sprayed onto the purified water filter screen 30, which can remove the stuck residues on the purified water filter screen 30, improve the filtering ability of the purified water filter screen 30, and extend its service life.

[0186] Specifically, the purified water filter screen 30 covers the backwashing member 55. The backwashing member 55 is disposed on the downstream side of the purified water filter screen 30, that is, the backwashing member 55 is disposed on the side of the purified water filter screen 30 facing the purified water outlet 122. After the backwashing member 55 sprays water onto the purified water filter screen 30, the stuck residues on the purified water filter screen 30 fall to the upstream side of the purified water filter screen 30, facilitating the discharge of the residues from the waste outlet 123.

[0187] Optionally, as Figure 8 shown, a plurality of spray holes 552 arranged along the rotation axis of the purified water filter screen 30 are provided on the backwashing member 55. Thus, the washing water sprayed from the plurality of spray holes 552 forms a spray ray extending along the rotation axis of the purified water filter screen 30. The spray ray of the plurality of spray holes 552 on the purified water filter screen 30 is long enough to fully spray away the stuck residues on the purified water filter screen 30.

[0188] In some embodiments, when the filtering device 100 further includes a circulation pump 65, the inlet end 651 of the circulation pump 65 communicates with the slag collection water outlet 112 and the purified water outlet 122, and the outlet end 652 of the circulation pump 65 communicates with the backwashing flow 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 of the circulation pump 65, which improves the flow rate of the washing water between the circulation pump 65 and the purified water chamber 12 and enhances the circulation efficiency of the washing water. The backwashing member 55 is received in the purified water chamber 12 and is located on the upstream side of the purified water filter screen 30. The backwashing member 55 communicates with the outlet end 652 of the circulation pump 65, and the filtered washing water in the purified water chamber 12 enters the inlet end 651 of the circulation pump 65. Spray holes 552 facing the purified water filter screen 30 are formed on the backwashing member 55, and the washing water flowing into the backwashing member 55 can be sprayed from the spray holes 552 onto the purified water filter screen 30 to remove the filter residues adhered to the surface of the purified water filter screen 30, reduce the possibility of blockage of the purified water filter screen 30, improve the cleanliness and water permeability of the purified water filter screen 30, reduce the loss of washing water, and enhance the filtering efficiency and filtering effect of the purified water filter screen 30.

[0189] Specifically, as Figure 8As shown, the filtering device 100 further includes: a flow channel plate 50, which is arranged at the bottom of the structural body 10. A clean water flow channel 51 is arranged inside the flow channel plate 50, and the clean water flow channel 51 communicates with the slag collection water outlet 112 and the clean water outlet 122. A backwashing member 55 is arranged on the top of the flow channel plate 50, and a water supply flow channel 53 communicating with the backwashing flow channel 551 is arranged inside the flow channel plate 50. Here, the flow channel plate 50 is used to connect the backwashing member 55, which has a high integration degree and is convenient for assembly. It can also reduce the number of parts and facilitate sealing.

[0190] Further, the backwashing member 55 is integrally formed on the top of the flow channel plate 50, and a water supply flow channel 53 communicating with the backwashing flow channel 551 is arranged inside the flow channel plate 50. That is to say, the outlet end 652 of the circulation pump 65 communicates with the water supply flow channel 53, and then flows from the water supply flow channel 53 to the backwashing flow channel 551. In this way, no additional pipes need to be provided, which can simplify the structure.

[0191] Specifically, as Figure 2 shown, the washing water flowing out from the outlet end 652 of the circulation pump 65 will flow in two directions. Most of the washing water flows to the washing link, and a small part of the washing water flows into the shunt pipe 56. The other end of the shunt pipe 56 is connected to the structural body 10 and communicates with the water supply flow channel 53, so as to supply the shunted washing water to the backwashing member 55.

[0192] In some embodiments, as Figure 9 and Figure 11 shown, a circulating water inlet pipe 193 is arranged at the bottom of the structural body 10. A spray arm flow channel 15 is arranged inside the structural body 10. The lower end of the spray arm flow channel 15 communicates with the circulating water inlet pipe 193, and the upper end of the spray arm flow channel 15 forms a spray arm interface 151 at the top of the structural body 10. With this setting, it is convenient to drive the filtered washing water through the circulation pump 65, flow into the circulating water inlet pipe 193, and then flow from the circulating water inlet pipe 193 into the spray arm flow channel 15.

[0193] The spray arm interface 151 here is used to install the spray arm, and the spray arm can be a fixed arm or a rotating arm. By introducing the washing water, the spray arm can spray the washing water onto the items to be washed, such as pots and bowls, to improve the cleanliness.

[0194] Specifically, at least two spray arm flow channels 15 are arranged inside the structural body 10. To enable each spray arm flow channel 15 to obtain a certain amount of washing water, the filtering device 100 further includes a water distribution valve 69, and the water distribution valve 69 is connected to the circulating water inlet pipe 193 to evenly distribute the inflowing water to different spray arm flow channels 15.

[0195] More specifically, one end of the shunt pipe 56 is connected to the circulating water inlet pipe 193 and is located upstream of the water distribution valve 69.

[0196] In some embodiments, as Figure 9 and Figure 10As shown, a water collecting cavity 14 is provided inside the structural main body 10. The water collecting cavity 14 is used to collect the washing water of the cleaning device 1000, so that it is convenient to discharge the washing water concentrated at the water collecting cavity 14 after the final washing is completed.

[0197] Specifically, the water collecting cavity 14 is connected to the slag collecting and discharging port 113, so that the residue collected in the slag collecting cavity 11 can be discharged together with the collected washing water from the water collecting cavity 14. Thus, the impact force of the washing water can be used to flush out the residue, reducing the phenomenon of the residue sticking to the wall during the flushing process.

[0198] Furthermore, as Figure 9 and Figure 10 shown, the water collecting cavity 14 and the slag collecting cavity 11 are separated by a one-way valve 61a, and the one-way valve 61a opens unidirectionally from the slag collecting cavity 11 to the water collecting cavity 1. In this way, when the water collecting cavity 14 is not draining water, the air pressure on the side of the water collecting cavity 14 can be slightly higher than that on the side of the slag collecting cavity 11, so that the one-way valve 61a closes the slag collecting and discharging port 113. Especially when the cleaning device 1000 is in the washing state and the circulation pump 65 is turned on to make the slag collecting cavity 11 in a negative pressure state, the non-draining water collecting cavity 14 has a higher air pressure than the slag collecting cavity 11, thus tightly closing the slag collecting and discharging port 113. In this way, the residue content in the washing water collected in the water collecting cavity 14 is small, which is convenient for collection and reuse. And the slag collecting cavity 11 is still in a continuous state of collecting and filtering slag.

[0199] When the water collecting cavity 14 drains water, due to the rapid emptying, the air pressure on the side of the water collecting cavity 14 drops rapidly. When its air pressure is lower than that on the side of the slag collecting cavity 11, the one-way valve 61a can be opened, so that the collected residue can be discharged from the slag collecting and discharging port 113 to the water collecting cavity 14, and then discharged from the water collecting cavity 14.

[0200] In some embodiments, the water collecting cavity 14 and the slag collecting cavity 11 are separated by a one-way valve 61a. When the circulation pump 65 is shut down and the water collecting cavity 14 drains water, the slag collecting cavity 11 is in a positive pressure state to open the one-way valve 61a. When the circulation pump 65 is turned on, it means the start of the washing process. When the circulation pump 65 is shut down, it means the end of the washing process. The switch of the slag collecting cavity 11 can immediately adjust the opening and closing state of the one-way valve 61a, and the slag discharging control is very flexible, without the need to separately set a controller.

[0201] Among them, the lowest point of the water collecting cavity 14 is set lower than the slag collecting and discharging port 113, which is convenient for emptying the residue in the slag collecting cavity 11 and reducing the accumulation at the slag collecting and discharging port 113.

[0202] In some embodiments, as Figure 10 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. The one-way valve 61a is abutted and installed on the first stepped surface 141. In this way, while facilitating the emptying of the residue in the slag collecting cavity 11, it is also convenient for the positioning and installation of the one-way valve 61a.

[0203] In some specific embodiments, such as Figure 11 shown, a sewage discharge port 175 is further provided on the structural body 10, and the sewage discharge port 175 is communicated with the slag collection and discharge port 113. A one-way valve 61a is provided at the slag collection and discharge port 113, and the one-way valve 61a is configured to open unidirectionally from the slag collection cavity 11 to the sewage discharge port 175. That is to say, when discharging slag, the residue finally discharges from the sewage discharge port 175.

[0204] Specifically, as Figure 2 shown, the water collection cavity 14 is communicated with the sewage discharge port 175, and the filtering device 100 further includes a drain valve 67 for opening and closing the sewage discharge port 175. The drain valve 67 is closed when the circulation pump 65 is working, and the circulation pump 65 is closed when the drain valve 67 is opened. In this way, when the circulation pump 65 is working, the slag collection cavity 11 is in a negative pressure state. At this time, the drain valve 67 is closed, and the water pressure in the water collection cavity 14 is relatively high, so as to tightly close the one-way valve 61a. When the circulation pump 65 is closed, the air pressure in the slag collection cavity 11 rises. At this time, the drain valve 67 is opened to reduce the water pressure in the water collection cavity 14, so that the residue can be automatically sucked into the water collection cavity 14 and finally washed away by the water flow from the sewage discharge port 175.

[0205] In some embodiments, such as Figure 3 shown, an initial filtration cavity 13 is further provided inside the structural body 10. The initial filtration cavity 13 has an initial filtration outlet 133, and the initial filtration outlet 133 is communicated with the purified cavity inlet 121. The filtering device 100 further includes an initial filter element 70, and the initial filter element 70 is used to filter the washing water entering the initial filtration cavity 13.

[0206] That is to say, before the residue enters the slag collection cavity 11 along with the water flow, there are at least two-stage filtrations. In this way, the residue is selected according to size, the load on the filter screen during each filtration is reduced, and the filtration effect is improved.

[0207] Specifically, as Figure 2 、 Figure 3 and Figure 9 shown, the initial filtration cavity 13 further includes an initial filtration vertical cavity 131, and the initial filtration outlet 133 is located on the outer peripheral wall of the initial filtration vertical cavity 131. As Figure 9 shown, the initial filter element 70 includes an initial filter cup cylinder 71 with first initial filter holes 701. The initial filter cup cylinder 71 is arranged inside the initial filtration cavity 13. The outer peripheral part of the initial filter cup cylinder 71 constitutes the initial filtration vertical cavity 131, and the inner peripheral part of the initial filter cup cylinder 71 constitutes the unfiltered initial collection cavity 16. That is to say, the initial filter cup cylinder 71 uses the entire cylindrical wall for filtration, with a large filtration area and high filtration efficiency. At this time, the washed water after initial filtration enters the purified water cavity 12 from the initial filtration outlet 133 on the outer periphery of the initial filtration vertical cavity 131, and the incoming water flow has a flowing power, washing the residue towards the waste outlet 123 to enter the slag collection cavity 11.

[0208] It should be noted that the maximum passing particle size of the primary filter cup cylinder 71 can be limited by the size of the first primary filter holes 701 on the primary filter cup cylinder 71. For example, when the width of the first primary filter holes 701 is set at 0.5 mm, the primary filter cup cylinder 71 can leave residues with a particle size exceeding 0.5 mm in the primary collection cavity 16, while residues with a particle size less than 0.1 mm may flow into the primary filter vertical cavity 131 with the washing water and enter the purified water cavity 12. Alternatively, at least one layer of filter cloth can be provided on the surface of the primary filter cup cylinder 71. The primary filter cup cylinder 71 is a rigid member for supporting the filter cloth, and the maximum passing particle size of the primary filter cup cylinder 71 is limited by the mesh size of the filter cloth.

[0209] Furthermore, as Figure 9 and Figure 10 shown, the primary filter member 70 further includes: a primary filter bottom wall 73 with second primary filter holes 702. The primary filter bottom wall 73 is connected to the bottom of the primary filter cup cylinder 71. The primary filter bottom wall 73 and the primary filter cup cylinder 71 form a filter cup, so that large-sized residues filtered out can be concentrated in the filter cup for convenient centralized cleaning.

[0210] It should be noted that the maximum passing particle size of the primary filter bottom wall 73 can be limited by the size of the second primary filter holes 702 on the primary filter bottom wall 73. For example, when the width of the second primary filter holes 702 is set at 3 mm, the primary filter bottom wall 73 can leave residues with a particle size exceeding 3 mm in the primary collection cavity 16. For residues with a particle size less than 3 mm, a relatively large part of the residues (residues with a particle size less than the maximum passing particle size of the primary filter cup cylinder 71) may pass through the primary filter cup cylinder 71, flow into the primary filter vertical cavity 131 with the washing water, and enter the purified water cavity 12. Alternatively, at least one layer of filter cloth can be provided on the surface of the primary filter bottom wall 73. The primary filter bottom wall 73 is a rigid member for supporting the filter cloth, and the maximum passing particle size of the primary filter bottom wall 73 is limited by the mesh size of the filter cloth.

[0211] Even further, as Figure 1 and Figure 7 shown, the primary filter member 70 further includes: a primary filter plate 72 with third primary filter holes 703. The primary filter plate 72 is located at the top of the structural body 10. An avoidance opening 721 is provided on the primary filter plate 72. The primary filter plate 72 is sleeved on the primary filter cup cylinder 71 through the avoidance 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 structural body 10. The primary filter horizontal cavity 132 communicates with the upper end of the primary filter vertical cavity 131.

[0212] This allows the washing water to be filtered out from the primary filter plate 72 and enter the primary filter horizontal cavity 132, then enter the primary filter vertical cavity 131, and then enter the purified water cavity 12 for filtration. Such an arrangement makes the primary filtration process have a large area, a fast filtration speed, and high efficiency.

[0213] It should be noted that the maximum passing particle size of the primary filter plate 72 can be restricted by the size of the third primary filter holes 703 on the primary filter plate 72. For example, when the width of the third primary filter holes 703 is set at 0.5 mm, the primary filter plate 72 can leave the residues with a particle size exceeding 0.5 mm above, while the residues with a particle size less than 0.5 mm may flow into the primary filter horizontal cavity 132 along with the washing water and enter the purified water cavity 12. Alternatively, at least one layer of filter cloth can be arranged on the surface of the primary filter plate 72. The primary filter plate 72 is a rigid part for supporting the filter cloth, and the maximum passing particle size of the primary filter plate 72 is restricted by the mesh size of the filter cloth.

[0214] In some specific embodiments, as Figure 7 shown, the primary filter member 70 further includes a cup rim portion 74 connected to the upper edge of the primary filter cup cylinder 71. The cup rim portion 74 is located above the primary filter plate 72. The cup rim portion 74 refers to the rim of the above-mentioned filter cup. The arrangement of the cup rim portion 74 can facilitate the user to pick up the filter cup for cleaning.

[0215] At the connection between the cup rim portion 74 and the primary filter cup cylinder 71, it is fitted at the avoidance opening 721 of the primary filter plate 72. Optionally, at the connection between the cup rim portion 74 and the primary filter cup cylinder 71 of the primary filter member 70, the shapes and sizes are the same as those of the avoidance opening 721, so as to achieve relative sealing at the connection and prevent residues from leaking.

[0216] Furthermore, slag passing holes 704 are provided on the cup rim portion 74, which facilitates the water flow to drive the residues to flow through the slag passing holes 704 and enter the primary collection cavity 16. Here, the sizes of the slag passing holes 704 are set relatively large, which is convenient for all larger residues to be concentrated in the primary collection cavity 16 for centralized treatment. It can reduce the amount of residues left above the primary filter plate 72 and avoid the residues left from affecting the washing effect.

[0217] Specifically, the cup rim portion 74 is annular, and a circle of slag passing holes 704 are provided on the cup rim portion 74.

[0218] In some embodiments, as Figure 2 and Figure 3 shown, the primary filter cup cylinder 71, the purified water filter screen 30 and the slag collection filter screen 20 are distributed in a triangular shape. In this way, the space that the structure main body 10 needs to provide for the three can be concentratedly arranged. On the one hand, the external dimension of the structure main body 10 can be reduced. On the other hand, the interval wall thickness between adjacent cavities can be controlled, which is beneficial to reducing the weight.

[0219] Specifically, as Figure 9 shown, when a water collection cavity 14 is provided in the structure main body 10, the water collection cavity 14 is located below the primary collection cavity 16. In this way, the water collection cavity 14 can collect the washing water from the primary collection cavity 16. On the one hand, when collecting water in this way after the washing is over, the water flow path is short and the water collection is fast. On the other hand, it is convenient for the processing and forming of the water collection cavity 14 and the primary collection cavity 16.

[0220] More specifically, the water collection cavity 14 is arranged below the primary collection cavity 16, and the water collection cavity 14 and the primary collection cavity 16 are separated by a primary filter bottom wall 73. Thus, the residues with particle sizes exceeding the maximum passing particle size of the primary filter bottom wall 73 remain in the primary collection cavity 16, that is, in the filter cup. And part of the residues with particle sizes smaller than the maximum passing particle size of the primary filter bottom wall 73 can fall into the water collection cavity 14. In this way, part of the residues will be stored in the water collection cavity 14 during the washing process. When draining water after the washing is completed, this part of the residues can be discharged with the water flow.

[0221] Optionally, the water collection cavity 14 is simultaneously located below the primary collection cavity 16 and the primary filter vertical cavity 131. When the filtration device 100 is operating, the water flow will be driven by the circulation pump 65 and enter the primary filter vertical cavity 131 after primary filtration from the cleaning space 201. The filtered washing water with small particle size residues enters the clean water cavity 12. Most of the washing water returns to the circulation pump 65 after re-filtration, and a small part of the washing water with a large amount of filtered small particle size residues enters the residue collection cavity 11. In the residue collection cavity 11, the washing water is filtered again, and the filtered washing water returns to the circulation pump 65, and the remaining residues stay in the residue collection cavity 11. During the filtration process, part of the residues in the primary collection cavity 16 will sink into the water collection cavity 14 with the water flow. As more and more residues sink into the water collection cavity 14, the washing water accumulated in the water collection cavity 14 is squeezed back into the primary filter cavity 13 and participates in the circulating flow of the washing water. Finally, after the filtration device 100 is used up, the washing water can flow into the water collection cavity 14 and be discharged from the water collection cavity 14, taking away the residues in the water collection cavity 14 and the residue collection cavity 11 while draining water. And the residues with larger sizes still remain in the filter cup and are taken out manually and poured out of the filter cup.

[0222] In the solution of the present application, the main chamber structures of the filtration device 100 are all formed on the structural main body 10. That is to say, the structural main body 10 is the main structure that supports the functions of the filtration device 100. For a clearer understanding of the functions of the filtration device 100, the following refers to Figure 11 and the structures of the structural main body 10 in the embodiments of the present invention are described in detail with reference to other relevant drawings.

[0223] According to the structural main body 10 of the embodiment of the present invention, a horizontally arranged primary filter vertical cavity 131, a clean water cavity 12 and a residue collection cavity 11 are provided inside the structural main body 10. As described above, the primary filter vertical cavity 131 can be equipped with a primary filter cup cylinder 71 for primary filtration. The clean water cavity 12 can be equipped with a clean water filter screen 30 for secondary filtration, and the residue collection cavity 11 is used to collect the residues left after filtration. A water collection cavity 14 is also provided inside the structural main body 10, which is used to collect the washing water flowing in from other cavities, so as to facilitate centralized drainage.

[0224] Among them, a primary filter outlet 133 is provided on the side wall surface S7 of the primary filter vertical cavity 131. The clean water cavity 12 has a clean cavity inlet 121, a clean water outlet 122 and a waste outlet 123, and the clean cavity inlet 121 is communicated with the primary filter outlet 133. Refer to Figure 11and Figure 9 The slag collection chamber 11 has a slag collection inlet 111 and a slag collection outlet 113. The slag collection inlet 111 communicates with the waste outlet 123, and the slag collection outlet 113 communicates with 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 at least the purified water outlet 122 for recycling.

[0225] Arranging the primary filtration vertical chamber 131, the purified water chamber 12, and the slag collection chamber 11 horizontally can reduce the overall occupied height and help control the height dimension of the structural body 10.

[0226] Specifically, as Figure 6 shown, the bottom wall surface S1 of the slag collection chamber 11 includes: a guiding bottom surface S11, and the height of the guiding bottom surface S11 gradually decreases in the direction towards the slag collection outlet 113. The lowest point of the water collection chamber 14 is lower than the slag collection outlet 113. This enables the residue to flow smoothly from the slag collection chamber 11 to the water collection chamber 14, improving the evacuation probability of the slag collection chamber 11.

[0227] In some embodiments, as Figure 2 and Figure 11 shown, a part of the structural body 10 is an intersecting wall column 180, and the primary filtration vertical chamber 131, the purified water chamber 12, and the slag collection chamber 11 are arranged around the intersecting wall column 180. The primary filtration vertical chamber 131, the purified water chamber 12, and the slag collection chamber 11 are generally triangularly distributed, and their arrangement is compact, occupying a small space, which is beneficial to reducing the external dimension of the structural body 10. With such an arrangement, the residue flows with the water in a relatively small space range for one circle, and the flow path is long, allowing the washing water therein to be fully separated and discharged during the flow.

[0228] In some embodiments, the part of the structural body 10 separating the primary filtration vertical chamber 131 and the purified water chamber 12 is the first wall plate 181. As Figure 2 and Figure 11 shown, one end of the first wall plate 181 is connected to the intersecting wall column 180, and the primary filtration outlet 133 and the purified chamber inlet 121 are provided on the first wall plate 181.

[0229] The part of the structural body 10 separating the purified water chamber 12 and the slag collection chamber 11 is the second wall plate 182. One end of the second wall plate 182 is connected to the intersecting wall column 180, and the waste outlet 123 and the slag collection inlet 111 are provided on the second wall plate 182. This enables the water flow to smoothly carry the unfiltered residue from the primary filtration vertical chamber 131 to the purified water chamber 12 and the slag collection chamber 11 during the sequential lateral flow from the primary filtration vertical chamber 131 to the purified water chamber 12 and the slag collection chamber 11, reducing the turbulence generated when the water flow enters one chamber from another, thereby reducing the water flow resistance and lowering the energy consumption.

[0230] In some embodiments, as Figure 2 and Figure 11As shown, the waste outlet 123 and the slag collection inlet 111 are provided at one end of the second wall panel 182 away from the intersecting wall column 180.

[0231] By setting the waste outlet 123 at one end of the second wall panel 182 away from the intersecting wall column 180 and with a large circumferential distance from the clean cavity inlet 121, the probability of the filtered residue flowing back from the clean cavity inlet 121 can be reduced. Moreover, the slag discharge channel 184 between the waste outlet 123 and the slag collection inlet 111 can be set shorter, which is convenient for processing. The shorter slag discharge channel 184 makes it difficult for the residue to block the slag discharge channel 184.

[0232] In some embodiments, as Figure 11 shown, an exhaust hole 124 communicating the primary filtration vertical cavity 131 and the clean water cavity 12 is provided on the first wall panel 181. This can balance the air pressure inside and outside the clean water cavity 12, allowing the washing water filtered out by the primary filtration vertical cavity 131 to smoothly enter the clean water cavity 12.

[0233] Specifically, as Figure 11 shown, the exhaust hole 124 is higher than the primary filtration outlet 133. In this way, the water flow in the primary filtration vertical cavity 131 flows from the primary filtration outlet 133 to the clean water cavity 12, and the water flow height is generally within the height range of the primary filtration outlet 133. And the exhaust hole 124 being higher than the primary filtration outlet 133 can prevent the water flow from flowing into the exhaust hole 124 and causing a water seal situation.

[0234] Specifically, as Figure 11 shown, the exhaust hole 124 is located on the side of the primary filtration outlet 133 close to the intersecting wall column 180. It can be understood that the water flow in the clean water cavity 12, according to the design, flows circumferentially from the clean cavity inlet 121 towards the waste outlet 123, and a large amount of washing water flows radially towards the central clean water outlet 122 during the flow process. The exhaust hole 124 is located on the side of the primary filtration outlet 133 close to the intersecting wall column 180, and the exhaust hole 124 is downstream of the clean cavity inlet 121 and the waste outlet 123 in the water flow direction in the clean water cavity 12, reducing the probability of the water flow and residue rushing towards the exhaust hole 124, thereby reducing the blockage probability of the exhaust hole 124.

[0235] In some embodiments, the slag collection inlet 111 is located on the side wall surface S2 of the slag collection cavity 11 and is higher than the slag collection water outlet 112 and the slag collection slag outlet 113. This can prevent the water flow and residue in the slag collection cavity 11 from flowing back from the slag collection inlet 111.

[0236] In some embodiments, the side wall surface of the slag collection cavity 11 opposite to the slag collection inlet 111 is the first arc surface S3-1. The two ends of the first arc surface S3-1 correspond to the slag collection inlet 111 and the slag collection and discharge outlet 113, and the middle of the first arc surface S3-1 protrudes away from the slag collection and water discharge outlet 112 relative to the two ends. In this way, when the water flow velocity is fast and drives the residue to rush into the slag collection cavity 11 from the slag collection inlet 111, the residue is ejected onto the first arc surface S3-1, and thus converges along the first arc surface S3-1 towards the slag collection and discharge outlet 113. In this way, it is beneficial to improve the concentration efficiency of the residue by means of the first arc surface S3-1.

[0237] Specifically, the area of the slag collection inlet 111 is larger than the flow-through area of the slag collection and discharge outlet 113. It can be understood that during the washing process, the slag collection inlet 111 is always open. The larger-area slag collection inlet 111 can improve the convenience of residue entry, while the smaller slag collection and discharge outlet 113 is convenient to close, facilitating the adjustment of the slag collection cavity 11 into a negative pressure state.

[0238] In some embodiments, the horizontal projection of the slag collection cavity 11 is strip-shaped. The side wall surface S2 of the slag collection cavity 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 oppositely arranged, and the second side wall surface S22 and the fourth side wall surface S24 are oppositely arranged.

[0239] The primary filtration vertical cavity 131 and the purified water cavity 12 are located on the side of the first side wall surface S21 away from the third side wall surface S23. The length of the first side wall surface S21 is greater than the lengths of the second side wall surface S22 and the fourth side wall surface S24, and the length of the third side wall surface S23 is greater than the lengths of the second side wall surface S22 and the fourth side wall surface S24.

[0240] Such an arrangement makes the overall occupied space of the three cavities close to a rectangle, which is convenient for the processing of the structural body 10.

[0241] In some embodiments, the purified water filter screen 30 is rotatably arranged in the purified water cavity 12, and the rotation direction of the purified water filter screen 30 is tangentially oriented towards the slag collection inlet 111 at the waste outlet 123. In this way, the residue thrown off from the purified water filter screen 30 can slide along the side wall surface S5 of the purified water cavity 12 and slide along the waste outlet 123 towards the slag collection inlet 111 when it encounters the waste outlet 123, entering the slag collection cavity 11. This helps the residue to smoothly enter the slag collection cavity 11 and reduces the accumulation of residue in the purified water cavity 12.

[0242] In some embodiments, such as Figure 3As shown, the slag collection inlet 111 is provided on the first side wall surface S21, and the edge of the slag collection inlet 111 is located on the second side wall surface S22. That is to say, when water flow with residues is injected, it can smoothly slide onto the second side wall surface S22, increasing the sliding speed of the residues along the wall, which helps the residues to continue to concentrate towards the slag collection and discharge outlet 113.

[0243] In some embodiments, such as Figure 2 and Figure 11 shown, the purified water cavity 12 is a cylindrical cavity, and the connection line between the center of the purified water cavity 12 and the waste outlet 123 is the slag discharge line L1.

[0244] The second side wall surface S22 extends along 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 along a direction perpendicular to the slag discharge line L1.

[0245] Here, the fact that the purified water cavity 12 is a cylindrical cavity helps the water flow with residues to obtain a stable centrifugal force when flowing along the side wall surface S5 of the purified water cavity 12, which thus helps the residues to be thrown out from the waste outlet 123 after encountering the waste outlet 123.

[0246] The slag discharge channel 184 between the waste outlet 123 and the slag collection inlet 111 is extended along a direction perpendicular to the slag discharge line L1, and the slag discharge channel 184 is close to being arranged tangentially to the purified water cavity 12, exactly consistent with the inertial force obtained by the residues at the waste outlet 123, so that the residues can quickly be discharged along the slag discharge channel 184 to the slag collection cavity 11. With such a setting, the residues can enter the slag collection cavity 11 at a relatively high speed, enabling the residues to concentrate towards the slag collection and discharge outlet 113 under the action of inertial force, improving the slag collection efficiency.

[0247] In some specific embodiments, such as Figure 3 shown, the third side wall surface S23 is the first arc surface S3-1, and the middle of the first arc surface S3-1 protrudes towards a direction away from the intersection wall column 180 relative to both ends. As Figure 2 shown, when the water flow velocity is fast and drives the residues to rush into the slag collection cavity 11 from the slag collection inlet 111, the residues are sprayed onto the first arc surface S3-1, and thus concentrate towards the slag collection and discharge outlet 113 along the first arc surface S3-1. In this way, it is beneficial to improve the concentration efficiency of the residues by means of the first arc surface S3-1.

[0248] In some specific embodiments, such as Figure 3 shown, the first side wall surface S21 is the second arc surface S1-1. As Figure 2 shown, the second arc surface S1-1 forms a convex angle 185 protruding towards the intersection wall column 180 at the intersection wall column 180, which can expand the capacity of the slag collection cavity 11.

[0249] Specifically, the slag collection chamber 11 further has a slag collection water outlet 112 provided on the bottom wall surface S1 of the slag collection chamber 11, and the slag collection water outlet 112 is arranged adjacent to the convex corner 185. At this time, the water flow slows down when flowing into the convex corner 185 and is likely to flow out from the slag collection water outlet 112. Moreover, when the slag collection water outlet 112 is provided here, a slag collection filter screen 20 can also be provided here. The slag collection filter screen 20 is located at the convex corner 185, and the convex corner 185 provides a moving space for the slag collection filter screen 20, which is beneficial to increasing the filtering area of the slag collection filter screen 20 to improve the filtering effect.

[0250] In some specific embodiments, such as Figure 6 and Figure 8 shown, the structural main body 10 includes a surrounding platform 114 provided on the bottom wall surface S1 of the slag collection chamber 11, and the surrounding platform 114 is arranged around the slag collection water outlet 112. This can make the slag collection filter screen 20 higher than the bottom wall surface S1 of the slag collection chamber 11, reducing the large amount of bottom residues flowing towards the slag collection water outlet 112 from the gap below the slag collection filter screen 20.

[0251] In some specific embodiments, the waste outlet 123 is higher than the bottom wall surface S6 of the purified water chamber 12. This can prevent the residues in the slag collection chamber 11 from being directly impacted by the water flow and returning to the purified water chamber 12.

[0252] In some specific embodiments, such as Figure 11 shown, the top of the structural main body 10 is provided with a slag collection cleaning port 171 communicating with the slag collection chamber 11 and a purified chamber cleaning port 172 communicating with the purified water chamber 12. In this way, during maintenance or cleaning, it is convenient to perform operations such as observation, cleaning, and maintenance from the slag collection cleaning port 171 and the purified chamber cleaning port 172.

[0253] In some specific embodiments, the top of the primary filter vertical chamber 131 is open, which is convenient for assembling the filter cup.

[0254] A mating flanging 192 is formed at the top edge of the structural main body 10. The mating flanging 192 and the top surface of the structural main body 10 enclose a primary filter horizontal chamber 132, and the primary filter horizontal chamber 132 communicates with the upper end of the primary filter vertical chamber 131. This is convenient for installing the primary filter plate 72 with the mating flanging 192, and finally making the primary filter plate 72 located at the top of the structural main body 10. In this way, the washing water can quickly filter out from above through the primary filter plate 72 and enter the primary filter horizontal chamber 132.

[0255] In some specific embodiments, such as Figure 9 and Figure 10As shown, the water collection chamber 14 is located below the primary filtration vertical chamber 131 and communicates with the primary filtration vertical chamber 131. The part of the structural body 10 that separates the water collection chamber 14 and the slag collection chamber 11 is the third wall plate 183, and the slag discharge opening 113 of the slag collection chamber is provided on the third wall plate 183. This can shorten the distance between the water collection chamber 14 and the slag collection chamber 11, making the third wall plate 183 thinner. On the one hand, it is convenient for weight reduction, and on the other hand, it shortens the slag discharge path, which is beneficial to emptying the residue in the slag collection chamber 11.

[0256] In some specific embodiments, as Figure 10 shown, the bottom wall surface S3 of the water collection chamber 14 is lower than the bottom wall surface S1 of the slag collection chamber 11, and a first stepped surface 141 is formed at the connection. On the one hand, this is convenient for emptying the residue in the slag collection chamber 11, and on the other hand, it is convenient to use the first stepped surface 141 to position the slag discharge valve 61, improving the assembly convenience of the slag discharge valve 61.

[0257] Specifically, an inner connection part 142 is formed at the connection between the side wall surface S4 of the water collection chamber 14 and the side wall surface S7 of the primary filtration vertical chamber 131. This facilitates placing the primary filtration cup cylinder 71 on the inner connection part 142, and the inner connection part 142 becomes the installation and positioning part of the primary filtration cup cylinder 71, facilitating the installation of the filter cup.

[0258] Specifically, the inner connection part 142 extends along the radial direction of the primary filtration vertical chamber 131, with a simple structure and convenient for stable assembly.

[0259] Furthermore, the inner connection part 142 is circular ring-shaped, and a bayonet is provided on the inner connection part 142. The primary filtration element 70 includes a buckle provided on the outer peripheral surface of the primary filtration cup cylinder 71, and the buckle is stuck in the bayonet.

[0260] In some specific embodiments, as Figure 11 shown, a drain pipe 191 is provided on the outer side surface of the structural body 10. One end of the drain pipe 191 communicates with the water collection chamber 14, the other end of the drain pipe 191 is open for installing a drain valve 67, and a sewage discharge port 175 is provided on the pipe wall of the drain pipe 191. With this setting, it is convenient for the assembly of the drain valve 67.

[0261] In some specific embodiments, as Figure 9 shown, a water inlet 194 is provided on the structural body 10, and the water inlet 194 is provided on the peripheral wall of the primary filtration vertical chamber 131, facilitating the introduction of water flow.

[0262] As Figure 12 shown, the cleaning device 1000 according to the embodiment of the present invention includes the structural body 10 described in the above embodiment. The cleaning device 1000 according to the embodiment of the present invention 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 elaborated here. The cleaning device 1000 further includes: a device main body 200. The structural body 10 is integrated into the device main body 200, and the device main body 200 forms a cleaning space V1.

[0263] Specifically, the structural body 10 is provided inside the slag collection chamber 11. The slag collection chamber 11 is located below the cleaning space V1, and the bottom of the cleaning space V1 is communicated with the slag collection inlet 111. Alternatively, a slag collection chamber 11 and a purified water chamber 12 are formed inside the structural body 10. The slag collection chamber 11 and the purified water chamber 12 are located below the cleaning space V1, and the bottom of the cleaning space V1 is communicated with the purified water chamber inlet 121. Alternatively, a primary filtration vertical chamber 131, a slag collection chamber 11, and a purified water chamber 12 are formed inside the structural body 10. The slag collection chamber 11 and the purified water chamber 12 are located below the cleaning space V1, and the bottom of the cleaning space V1 is communicated with the purified water chamber inlet 121.

[0264] For the cleaning device 1000 according to the embodiment of the present invention, the use of the filtering device 100 can improve the slag filtering effect of the washing water, can provide cleaner washing water for recycling, and improve the washing cleanliness. Moreover, the service life of each filter screen in this filtering device 100 is relatively long, and the filtering effect can be maintained well for a long time.
