[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0050] This embodiment provides a filtering structure, such as Figures 1-2 As shown, the structure includes a cover 10, a surrounding wall 20, and a filter element 30. The surrounding wall 20 is located at the bottom of the cover 10 and is arranged circumferentially along the cover 10, forming an internal receiving cavity. The filter element 30 is provided with a plurality of filter holes 32 and a through hole 33 is provided axially, through which an external sewage pipe can extend into the filter element 30. When the filter element 30 is in the filtering position, it is housed in the receiving cavity. The filter element 30 is pivotally connected to the surrounding wall 20, and at least part of the filter element 30 can be flipped out of the receiving cavity around the pivot position to clean the residue inside the filter element 30.

[0051] In this structure, wastewater containing residue can enter the filter element 30 through the external drain pipe, that is, into the receiving cavity. Under gravity, the wastewater will leak out through the filter holes 32 and into the wastewater tank, but the residue will remain inside the filter element 30. However, with increased usage time, the filter structure needs timely cleaning. When cleaning is required, simply separate the filter structure from the external drain pipe and flip the filter element 30 to the outside of the receiving cavity to remove the residue. The structure is simple and easy to operate, improving cleaning convenience while ensuring power efficiency.

[0052] Specifically, such as Figure 1 and 2As shown, the bottom of the filter element 30 is evenly provided with a plurality of filter holes 32, and / or the sidewalls of the filter element 30 are provided with a plurality of filter holes 32 at intervals. This arrangement allows wastewater to flow out from the bottom and / or sidewalls of the filter element 30, thereby significantly improving the flow of filtered water and ensuring a good filtration effect.

[0053] It should be noted that in this embodiment, filter holes 32 are provided on both the bottom and sidewalls of the filter element 30, and the multiple filter holes 32 on the sidewalls are arranged in a matrix. This arrangement ensures that sewage can flow out from both the bottom and sidewalls of the filter element 30, thereby ensuring the high efficiency of water filtration; at the same time, the uniform arrangement of the filter holes 32 can also increase the smoothness and uniformity of the water output from the filter element 30, effectively avoiding clogging.

[0054] In addition, such as Figure 1 and Figure 2 As shown, the side wall of the filter element 30 is provided with a rotating shaft 34, which is pivotally connected to the surrounding wall 20. This arrangement further simplifies the overall structure, reduces production costs and operational difficulty, and ensures good operational convenience. In this embodiment, two rotating shafts 34 are symmetrically arranged on the side wall, and both rotating shafts 34 are pivotally connected to the surrounding wall 20 simultaneously. This not only simplifies the structure but also improves the stability and smoothness of the filter element 30's rotation.

[0055] It should be noted that, as Figure 2 As shown, the sidewall has a matrix of multiple filter holes 32, and the rotating shaft 34 is set at the interval of the matrix, which not only facilitates processing, but also ensures structural strength and avoids breakage.

[0056] In addition, such as Figure 1 and Figure 2 As shown, a flap 31 is also provided on the side of the filter element 30 away from the rotating shaft 34. When the filter element 30 is in the filtering position, the free end of the flap 31 is outside the receiving cavity. When the flap 31 is pulled away from the cover 10, the filter element 30 can at least partially flip out of the receiving cavity. When it is necessary to clean the residue inside the filter element 30, the operator only needs to pull the free end of the flap 31. Under the action of the rotating shaft 34, the filter element 30 can be flipped out of the receiving cavity, and then the residue can be cleaned. The structure is simple and the operation is convenient. In addition, the structure of the flap 31 facing the rotating shaft 34 makes the flipping process more labor-saving, which greatly improves the convenience and efficiency of cleaning.

[0057] Furthermore, considering that when the filter element 30 is in the filtering position, the side with the flap 31 may sag under the influence of gravity, thus affecting the filtering effect, to solve this problem, when the filter element 30 is in the filtering position, the flap 31 and the enclosure wall 20 can be engaged with each other. That is, when filtering is needed, the filter element 30 is rotated back into the receiving cavity, and the flap 31 is engaged with the enclosure wall 20 to ensure the stability of filtering; when cleaning is needed, the flap 31 is pulled outward to disengage the filter element 30 from the enclosure wall 20.

[0058] It should be noted that, as Figure 2 As shown, in this embodiment, the interior of the enclosure 20 is provided with a protrusion 21, and the flap 31 is provided with a locking hole 311. When the filter element 30 is rotated to the filtering position, the protrusion 21 will first abut against the flap 31, causing the flap 31 to deform slightly towards the side wall (there is a certain gap between the flap 31 and the side wall) until the protrusion 21 is locked into the locking hole 311, and then the flap 31 automatically resets, thus completing the locking assembly. When it is necessary to clean the filter element 30, the operator can first press the free end of the flap 31 towards the side wall, which will disengage the protrusion 21 from the locking hole 311. At this time, one side of the flap 31 is no longer restricted, so the filter element 30 can continue to be rotated to complete the subsequent cleaning work.

[0059] It should be further noted that this filter structure is typically used with a wastewater tank; therefore, when cleaning is required, the filter structure should first be removed from the wastewater tank. Therefore, if... Figure 1 and Figure 2 As shown, a handle 40 is provided on the top of the cover 10. Operators can pull the handle 40 to remove the entire filter structure from the sewage tank. After removal, the residue inside the filter element 30 can be cleaned, thereby further improving the convenience of cleaning and ensuring a good user experience.

[0060] This embodiment also provides a sewage tank, such as Figure 3 and Figure 4 As shown, the sewage tank includes a shell 100 and the aforementioned filter structure; a sewage tank 130 is provided inside the shell 100, a sludge suction pipe 140 communicating with the sewage tank 130 is provided at the bottom, and an installation port is provided at the top; the filter structure is installed into the sewage tank 130 from the installation port, and the sludge suction pipe 140 can at least partially extend into the filter element 30 through the through hole 33, so that sewage can enter the receiving cavity through the sludge suction pipe 140, be filtered by the filter element 30 and stored in the sewage tank 130, and the residue in the sewage can remain in the filter element 30.

[0061] Wastewater containing residue enters the filter element 30 through the suction pipe 140. The wastewater is stored in the wastewater tank 130 through the filter holes 32, while the residue remains inside the filter element 30. When cleaning is required, simply pull the handle 40 to remove the filter structure from the wastewater tank, and then continue cleaning the filter element 30. The wastewater can be directly discharged from the wastewater tank 130, thereby significantly improving the treatment effect of separating wastewater from residue.

[0062] Specifically, such as Figure 3 and Figure 4 As shown, the housing 100 includes an upper housing 110 and a lower housing 120, with a wastewater tank 130 disposed in the lower housing 120. The upper housing 110 and the lower housing 120 are detachably connected. This arrangement not only facilitates the removal of the upper housing 110, thereby improving wastewater treatment efficiency, but also significantly enhances the convenience of subsequent maintenance.

[0063] This embodiment also provides a floor brush, such as Figure 5 and Figure 7 As shown, the floor brush includes a body 200 and the aforementioned wastewater tank; a negative pressure mechanism is provided inside the body 200, and a floor brush roller 210 is provided on one side of the body 200; the wastewater tank is located on the body 200, the negative pressure structure is connected to the wastewater tank 130, and a sludge suction channel 250 is also provided inside the body 200. One end of the sludge suction channel 250 is connected to the sludge suction pipe 140, and the other end of the sludge suction channel 250 forms a sludge suction gap with the floor brush roller 210. The negative pressure structure can create a negative pressure effect in the wastewater tank 130, and the negative pressure effect can be transmitted to the sludge suction gap so as to suck the wastewater into the receiving cavity.

[0064] When the floor brush passes over stains on the floor, the negative pressure generated by the negative pressure structure can be transmitted to the dirt extraction gap. As the floor brush roller 210 rotates, it can absorb the sewage mixed with residue into the dirt extraction channel 250, and then enter the filter element 30 through the dirt extraction pipe 140. The sewage flows into the sewage tank 130 through the filter holes 32, and the residue remains in the filter element 30. In addition, the floor brush roller 210 can also clean the floor, thus producing a good cleaning effect.

[0065] Specifically, such as Figures 5-7 As shown, the negative pressure structure includes a negative pressure component 220, a negative pressure channel 230, and a filter cotton 240. The negative pressure component 220 is disposed within the body 200, and the lower housing 120 is provided with a suction port 150. The two ends of the negative pressure channel 230 are connected to the suction port 150 and the negative pressure component 220, and the filter cotton 240 is disposed at the suction port 150. This arrangement is not only simple in structure but also relatively compact, which fully improves the space utilization rate. At the same time, the filter cotton 240 can filter larger impurities or particulate matter in the gas, avoiding blockage inside the body 200.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
