Referring to fig. 1-2, the present embodiment provides a filter assembly comprising a filter cartridge 1 and a filter element 2.

Specifically, the filter box 1 comprises a box body 11 and a box cover 12 covered on the box body 11, and the filter element 2 is arranged in the box body 11, so that sewage entering the box body 11 is filtered, and in the process, the box cover 12 prevents the sewage from splashing out of the top opening of the box body 11. When the filter element 2 needs to be replaced, the box cover 12 is opened, and the filter element 2 is taken out of the box body 11.

Considering that part of the sewage may be sputtered to the top opening of the case 11 during the filtering process, oozes out from the junction of the case cover 12 and the case 11, referring to fig. 3, the case cover 12 of this embodiment includes a cover body 121, a handle 122 disposed on the top of the cover body 121, and a sealing ring 123 sleeved on the edge of the cover body 121. When the cover 121 is covered on the top opening of the case 11, the sealing ring 123 is located between the cover 121 and the opening of the case 11, thereby enhancing the sealing property between the case cover 12 and the case 11. Of course, in the process of opening the cover 121, the friction force between the sealing ring 123 and the opening edge of the box 11 can increase the opening difficulty of the cover 121, so that the cover 121 is difficult to be directly opened by directly operating the edge of the cover 121, and at this time, the cover 121 can be conveniently opened by operating the handle 122.

The installation mode of the box cover 12 on the box body 11 is not limited, for example, in this embodiment, the cover body 121 is rotatably arranged at the top opening of the box body 11, the buckle 1211 is installed on the cover body 121, the cover body 121 is locked on the box body 11 through the buckle 1211 after the cover closing action is completed, and if the filter box 1 is impacted and rocked, the cover body 121 can be prevented from being accidentally opened.

Referring to fig. 2, 4-8, the filter element 2 includes a filter plate 21 and a screen (not shown). A filter hole 211 for installing a filter screen is formed in the middle of the filter plate 21, and the filter screen is installed at the filter hole 211. The filter screen can be fixed in the filter hole 211 department, realizes the maintenance of filter 2 through wasing the filter screen, and the filter screen also can be installed in the filter hole 211 department through common detachable connected mode, realizes the maintenance of filter 2 through changing the filter screen.

The inner walls of the left and right sides of the box body 11 are provided with supporting steps 111, and the supporting steps 111 can be bumps, ribs or concave side walls of the box body 11 towards the middle cavity of the box body 11 in the embodiment. The left and right side edges of the filter plate 21 are respectively abutted against the two support steps 111 so that the middle portion of the filter plate 21 is disposed obliquely with respect to the bottom wall of the case 11. When the sewage reaches the filter screen, impurities in the sewage are intercepted by the filter screen, and a part of impurities slide down to the bottom of the filter plate 21 along the surface of the filter plate 21 under the action of gravity. Of course, because the filter screen surface is comparatively coarse, can cause great hindrance to the landing of some impurity, consequently also have a considerable part impurity to stay on the surface of filter screen for the filter screen takes place deformation, and the deformation of filter screen can be acted on filter plate 21 again, makes the filter plate take place deformation.

In order to achieve a stable installation of the filter plates 21 in the cassette 11, it is common in the prior art to locate the top and bottom of the filter plates 21 in the filter cassette 1, such as a catch or screw. Whereby the top and bottom of the filter plate 21 are supported and thus the deformation amount is small, and the filter plate 21 mainly deforms to concentrate in the middle portion of the filter plate 21, which exhibits a tendency to sink downward. The left and right edges of the middle part of the filter plate 21 may generate a certain gap with the inner wall of the box 11 due to deformation, and the sewage may directly reach the lower part of the filter plate 21 through the gap without passing through the filter screen and flow out of the box 11, thereby affecting the filtering effect of the sewage.

In the present embodiment, however, due to the supporting effect of the two supporting steps 111 on the edge of the filter plate 21, the downward sagging tendency of the filter plate 21 is effectively suppressed, so that the deformation amount of the edge of the filter plate 21 is reduced, and no obvious gap is generated between the edge of the filter plate 21 and the inner wall of the case 11. Therefore, the filtering effect of the sewage is obviously improved. In addition, since the filter screen is disposed at the middle position of the filter plate 21 through the filter holes 211, the support step 111 at the edge of the filter plate 21 is prevented from being damaged by the support step 111, and the normal filtering operation thereof is not hindered.

When the filter assembly is in place, the filter plate 21 has an inclination angle with respect to the horizontal, wherein the top of the filter plate 21 is located on the rear side of the bottom of the filter plate 21.

Preferably, the filter element 2 further includes a pressing plate 212, where the pressing plate 212 is disposed at a rear side of a top edge of the filter plate 21, that is, a side of the top edge of the filter plate 21 away from a bottom of the filter plate 21, and one of the pressing plates 212 may be formed by extending the top edge of the filter plate 21 toward the rear side, so that the pressing plate 212 is an extending structure of the filter plate 21. The pressing plate 212 is arranged in a horizontal mode, after the box cover 12 is covered on the opening of the top of the box body 11, the pressing plate 212 is pressed on the supporting step 111, and the top of the filter plate 21 is positioned by matching the box cover 12 with the supporting step 111. The lid 12 is normally not opened, and is usually only required to be opened when maintenance and cleaning of the filter element 2 are required, so that after the lid 12 is opened, the filter plate 21 immediately loses a top positioning effect, and the filter plate 21 is conveniently taken out.

The rear side of the pressure plate 212, that is, the side of the pressure plate 212 away from the filter plate 21, is provided with an operation plate 214, and the operation plate 214 is provided with an operation hole 2141, and the operation hole 2141 provides a space for movement and action of a finger of a user. After the lid 12 is opened, a user may extend his/her finger through the operation hole 2141 to below the operation plate 214, and then bend his/her finger tip to contact the lower bottom surface of the operation plate 214 to form a force application point, thereby facilitating the user to detach the filter element 2.

In order to reduce discomfort of contact between the finger and the edge of the operation hole 2141, the edge of the operation hole 2141 is covered with a protection rib 2142, and the protection rib 2142 may be made of a flexible material such as sponge. Of course, the protective ribs 2142 need a certain thickness to ensure the above effect is obvious. For this situation, the rear side edge of the pressing plate 212 in this embodiment, that is, the edge of the pressing plate 212 away from the filter plate 21, extends downward to form the avoidance plate 213, and the operation plate 214 extends from the bottom edge of the avoidance plate 213 to the rear side, that is, in the direction away from the filter plate 21, so that the operation plate 214 is pulled away from the box cover 12 by a certain distance through the avoidance plate 213, so that the protection ribs 2142 can avoid the box cover 12, and the protection ribs 2142 are prevented from affecting the normal covering process of the box cover 12.

The avoiding plate 213 may be moved by the lid 12 when the pressing plate 212 is pressed down, so as to drive the operation plate 214 to move in the horizontal direction, so that the rear edge of the operation plate 214, that is, the edge far away from the filter plate 21, is in clearance fit with the inner wall of the box body 11, so that the operation plate 214 has a certain movable space, and the closing state of the lid 12 is prevented from being affected. Of course, the gap is typically small. A part of the escape plate 213 is also fitted to the support step 111, whereby the filter sheet 21, the pressure plate 212 and the escape plate 213 as a whole cover the support step 111, so that the filter element 2 as a whole is supported more stably on the support step 111.

The bottom wall of the box body 11 is provided with a positioning groove 112, the bottom of the filter plate 21 is bent towards the direction vertical to the bottom wall of the filter box 1 to form an inserting part 215, and the inserting part 215 is inserted into the positioning groove 112, so that the bottom of the filter plate 21 is positioned in the box body 11. Because the plug-in portion 215 is perpendicular to the bottom wall of the box 11, the filter plate 21 can only be assembled and disassembled in the direction perpendicular to the bottom wall of the box 11, so that the filter plate 21 cannot displace in the horizontal direction during the assembly and disassembly process, and the operation plate 214 cannot be blocked by the inner wall of the box 11.

Because the positioning groove 112 is not deep due to the process conditions, a part of the plugging portion 215 is located outside the positioning groove 112, so that the filter screen cannot enter the positioning groove 112. The inner walls of the left side and the right side of the box body 11 are further provided with extrusion blocks 113, the two extrusion blocks 113 and the two supporting steps 111 are respectively corresponding, the extrusion blocks 113 are located on the front sides of the corresponding supporting steps 111, the extrusion blocks 113 press the parts of the plug-in parts 215 located outside the positioning grooves 112 on the supporting steps 111, the extrusion blocks 113 are matched with the supporting steps 111 to assist in positioning the bottom of the filter plate 21 in the horizontal direction, and meanwhile disassembly and assembly of the filter plate 21 in the vertical direction are not affected.

In this embodiment, the sewage is sprayed onto the filter screen on the filter plate 21, specifically, a lifting step 114 is provided on the inner wall of the box 11, a water inlet nozzle 1141 is provided on the lifting step 114, and the lifting step 114 is located at the front side of the extrusion block 113, so that the water inlet nozzle 1141 is located at the front side of the filter plate 21, i.e. the side far away from the pressure plate 212. Wherein the water inlet nozzle 1141 is lifted up by the lifting step 114 to make the discharged sewage more easily reach the high filter screen. If more impurities exist on the filter screen positioned at the high position, the excessive impurities can slide downwards under the action of gravity, the blockage is not easy to occur, and the impurities on the filter screen positioned at the low position can only be accumulated, so that the blockage is relatively easy to occur. Therefore, the sewage is sprayed to the filter screen at a higher position, so that the sewage can be effectively filtered by the filter element 2 for a longer time, and the maintenance frequency of the filter element 2 is reduced.

In addition, the impurities sliding from the filter screen are accumulated between the plug-in part 215 and the lifting step 114, and the lifting step 114 also reduces the space in front of the plug-in part 215, so that the accumulated impurities are accumulated in a smaller range, and the impurities are more concentrated, thereby cleaning the inside of the box 11 more conveniently when the filter element 2 is maintained.

The bottom wall of the box 11 is provided with a water outlet 115, and the water outlet 115 is positioned at the rear side of the filter plate 21, namely, the side far away from the water inlet nozzle 1141. After the large-particle impurities are removed by filtering with a filter screen, the sewage drops onto the bottom wall of the box body 11 at the rear side of the filter plate 21, finally flows out of the box body 11 through the water outlet 115, and is used for mopping by a cleaning robot. As can be seen from the foregoing, the space in front of the plug-in portion 215 is relatively narrow and is located at the bottom of the filter plate 21, so that the space in front of the plug-in portion 215 is most easily filled with impurities, and the filtered sewage in the rear of the plug-in portion 215 is not easily returned to the front of the plug-in portion 215, so as to inhibit the increase of the humidity of the impurities located in the front of the plug-in portion 215, thereby helping to inhibit the bacterial growth in the impurities.

Example 2:

referring to fig. 9, the difference between this embodiment and embodiment 1 is that the bottom of the lid 12 is provided with the ultraviolet lamp 124, and the ultraviolet lamp 124 has a sterilizing effect on the impurities in the box body, and meanwhile, since the ultraviolet lamp 124 is located between the two supporting steps 111, the lid 12 can avoid the supporting steps 111 by the ultraviolet lamp 124 after being covered.

Example 3:

this embodiment provides a cleaning base station comprising the filter assembly of embodiment 1 or embodiment 2. The cleaning robot acquires clean water from the cleaning base station to clean the floor, collects sewage generated by the floor cleaning, sends the sewage to the filtering assembly to carry out primary filtering, and filters and converts the sewage after the primary filtering into clean water for a plurality of times, so that the clean water is reused for the floor cleaning robot to clean the floor.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
