Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the commodity or device including said element.

[0046] In the related art, if it is necessary to clean the inner wall of the sewage bucket, the cleaning device needs to be placed in the base station, then the sewage bucket is opened, and the inner wall of the sewage bucket is rinsed through a nozzle extended from the base station. The sewage bucket flushing method provided in the related art requires a base station with a relatively complex structure, and since at least one nozzle needs to be separately provided in the base station, the nozzle occupies a relatively large space in the base station. In addition, the operation steps required during the cleaning process of the sewage bucket are complex, which is not conducive to simple operation by the user and affects the user experience.

[0047] The embodiments of the present disclosure provide a sewage bucket assembly and a cleaning device. The sewage bucket assembly includes: a sewage bucket having a sewage inlet and configured to hold sewage; a filter screen assembly detachably disposed on the top of the sewage bucket, the filter screen assembly including a filter screen support; and a spraying assembly rotatably disposed at the bottom of the filter screen support and configured to clean the sewage bucket.

[0048] The sewage bucket assembly provided by the present disclosure includes a spraying assembly, and the spraying assembly is arranged inside the sewage bucket. The inner wall of the sewage bucket can be cleaned through the spraying assembly. In addition, since the spraying assembly is arranged at the bottom of the filter assembly, the spraying assembly can not only clean the inner side wall of the sewage bucket, but also clean the sewage inlet of the sewage bucket, improving the cleaning intensity of the inside of the sewage bucket and having the advantage of simple operation, which is beneficial to the user's convenient operation and improves the user's experience.

[0049] In view of this, the optional embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0050] A first aspect of an embodiment of the present disclosure provides a sewage bucket assembly 1000, as Figure 1 shown, the sewage bucket assembly 1000 includes a sewage bucket 100, a filter assembly 200, and a spraying assembly 300.

[0051] The sewage bucket 100 is used to hold sewage. A sewage inlet 101 is provided on the side wall of the sewage bucket 100 or at a position close to the side wall of the sewage bucket 100, and sewage enters the sewage bucket 100 through the sewage inlet 101.

[0052] In some embodiments, a shielding portion 120 is provided at the edge of the sewage inlet 101. The shielding portion 120 can be a dome structure, configured to prevent sewage from splashing when entering the sewage inlet 101, resulting in the spraying assembly 300 being contaminated by sewage. Specifically, when sewage flows from the outside of the sewage bucket 100 to the sewage inlet 101, due to the certain flow rate of the sewage itself, at least part of the sewage flushes the sewage inlet 101 during the process of the sewage passing through the sewage inlet 101, resulting in sewage splashing at the sewage inlet 101. The dome-shaped shielding portion 120 can block the sewage splashing droplets from contaminating the spraying structure from multiple angles.

[0053] In some embodiments, the sewage bucket assembly 1000 further includes a filter assembly 200. The filter assembly 200 is detachably arranged on the top of the sewage bucket 100, configured to prevent the air that may carry impurities inhaled by the filtering fan. The filter assembly 200 includes a filter support 210 and a filter 220. As Figure 4 、 Figure 5As shown, the filter screen assembly 200 is disposed at the top of the sewage bucket 100. The filter screen 220 is located at the top of the filter screen bracket 210 and is detachably connected to the filter screen bracket 210. The bottom of the filter screen bracket 210 faces the space for storing sewage inside the sewage bucket 100. The filter screen bracket 210 is configured to support the filter screen 220 through an air passage. The filter screen bracket 210 includes an air inlet 201. The air inlet 201 is disposed on the side of the filter screen bracket 210 and is communicated with the internal air passage of the filter screen bracket 210, configured to allow external air to enter the internal air passage of the filter screen bracket 210. Specifically, the external air can be inhaled into the ventilation pipeline inside the filter screen bracket 210 through the air inlet 201 under the action of a fan, then enter the filter screen 220, and be discharged from the sewage bucket assembly 1000 after being filtered by the filter screen 220.

[0054] In some embodiments, the filter screen bracket 210 further includes a partition 211. The partition 211 is disposed on the bottom wall of the filter screen bracket 210 and extends along the plane where the bottom wall is located, configured to prevent the cleaning liquid sprayed by the spraying assembly 300 from entering the air inlet 201. If there is liquid at the air inlet 201, the liquid is very likely to be inhaled into the inside of the fan under the action of wind, causing water to enter the fan, which is not conducive to the continuous use of the product.

[0055] In some embodiments, the sewage bucket assembly 1000 further includes a spraying assembly 300, as Figure 1 shown. In the height direction of the sewage bucket 100, the lowest end of the spraying assembly 300 is higher than the sewage inlet 101 and the shielding portion 120, so as to avoid sewage splashing and polluting the spraying assembly 300 when sewage enters the sewage inlet 101, resulting in the spraying assembly 300 being contaminated with dirt and dust.

[0056] In some embodiments, the spraying assembly 300 includes: a spraying assembly body 310 and a spray head 320, as Figure 6 shown. The spraying assembly body 310 can be a spherical structure. The spraying assembly body 310 is configured to accommodate the cleaning liquid. The spraying assembly body 310 includes a plurality of water outlet holes 302. The water outlet holes 302 are disposed on the side facing the bottom of the sewage bucket 100, configured to pass at least part of the cleaning liquid. The cleaning liquid can flow out of the spraying assembly body 310 through the water outlet holes 302, so that the cleaning liquid flows into the sewage bucket 100 to assist in cleaning the sewage bucket 100.

[0057] It should be noted that the present disclosure does not specifically limit the type of the cleaning liquid. The cleaning liquid can be clean water, detergent, or clean water containing detergent, as long as it can clean the sewage bucket 100.

[0058] In some embodiments, the spray head 320 extends along the spray assembly body 310 towards the side wall of the sewage bucket 100 and is configured to freely rotate under the action of the fluid ejection pressure to clean the sewage bucket 100. Specifically, the spray head 320 includes a nozzle 301, and the nozzle 301 is disposed on the side surface of the spray head 320 for spraying water towards the side wall of the sewage bucket 100.

[0059] Specifically, in response to the cleaning liquid flowing into the interior of the spray assembly body 310, due to the certain water pressure of the cleaning liquid itself, under the action of the water pressure, the cleaning liquid is ejected from the spray head 320 and sprayed towards the inner wall of the sewage bucket 100 to achieve the cleaning of the inner wall of the sewage bucket 100. Each nozzle 301 is disposed on the upstream side corresponding to the rotation direction of the spray head 320, so that the spray assembly 300 freely rotates under the action of the water pressure.

[0060] In some embodiments, in order to improve the cleaning efficiency of the spray assembly 300 on the inner wall of the sewage bucket 100, at least two or more spray heads 320 of the spray assembly 300 are provided, and the water spraying direction of the nozzle 301 is substantially perpendicular to the extending direction of the spray head 320.

[0061] As Figure 6 shown, the spray assembly 300 has three spray heads 320, and the three spray heads 320 are approximately in the same plane. The direction of the nozzle 301 is substantially perpendicular to the extending direction of the spray head 320. When the cleaning liquid is injected into the spray assembly body 310, the cleaning liquid will flow out from the nozzles 301 of the three spray heads 320 respectively. In response to the three nozzles 301 spraying the cleaning liquid simultaneously, thus, due to the principle related to fluid dynamics, under the reaction force of the ejected liquid column, the spray head 320 is pushed to rotate towards the upstream direction of the liquid ejection, and the rotation direction of the spray assembly 300 is as Figure 6 shown.

[0062] In some embodiments, the spray assembly 300 further includes: a sleeve and a hollow rotating shaft 330. The sleeve is connected to the filter screen bracket 210 so that at least a part of the spray assembly 300 is installed inside the filter screen bracket 210. A bearing may be provided between the hollow rotating shaft 330 and the sleeve. Specifically, one end or a part of the hollow rotating shaft 330 is rotatably connected to the sleeve, and the other end of the hollow rotating shaft 330 is connected to the spray assembly body 310 and is configured to enable the cleaning liquid to enter the spray assembly body 310 through the hollow rotating shaft 330.

[0063] The hollow rotating shaft 330, the main body 310 of the spraying assembly, and the spray head 320 are an integral structural member. In response to the rotation of the hollow rotating shaft 330 relative to the sleeve, the main body 310 of the spraying assembly and the spray head 320 rotate synchronously with the hollow rotating shaft 330. The cleaning liquid can flow into the main body 310 of the spraying assembly through the hollow rotating shaft 330 and is ejected from the nozzle 301 of the spray head 320 under the action of liquid pressure. As Figure 6 shown, each nozzle 301 is arranged on the upstream side corresponding to the rotation direction of the spray head 320 so that it can rotate freely under the action of water pressure. Specifically, the axis of the hollow rotating shaft 330 is substantially perpendicular to the extending direction of the spray head 320. In response to the cleaning liquid being ejected from the three nozzles 301 simultaneously, under the reaction force of the ejected liquid column, the three spray heads 320 rotate around the axis of the hollow rotating shaft 330 towards the upstream direction of the liquid ejection.

[0064] The rotation of the spraying assembly 300 is achieved by using the principle of fluid mechanics. When water flows out through the nozzle 301, due to the breaking of symmetry, the flowing water will generate a reverse pressure, and this reverse pressure will cause the direction of the water flow to deflect, thereby generating a certain torque. The rotating shaft of the sleeve is made of an elastic material. When the rotating shaft bears the torque of the water flow, it will undergo a slight deformation, thereby driving the hollow rotating shaft 330 to generate a rotational motion.

[0065] In some embodiments, the extending directions of different spray heads 320 are different, and the included angles between the water spraying directions of different spray heads 320 and the rotation plane of the spraying assembly 300 are also different.

[0066] As Figure 7 、 Figure 8 shown, the spraying assembly 300 includes a plurality of spray heads 320, including: a first spray head 321, a second spray head 322, and a third spray head 323. The first spray head 321, the second spray head 322, and the third spray head 323 are respectively provided with a first nozzle 301, a second nozzle 301, and a third nozzle 301. In the rotation direction of the spraying assembly 300, the first spray head 321 is located in the upstream direction of the second spray head 322; the second spray head 322 is located in the upstream direction of the third spray head 323; the third spray head 323 is located in the upstream direction of the first spray head 321.

[0067] In some embodiments, the angle between the water spraying direction of the first nozzle 321 and the rotation plane of the spraying assembly 300 is α, the angle between the water spraying direction of the second nozzle 322 and the rotation plane of the spraying assembly 300 is β, and the angle between the water spraying direction of the third nozzle 323 and the rotation plane of the spraying assembly 300 is γ. ∠α > ∠β > ∠γ. The nozzles 301 with different water spraying directions can spray the cleaning liquid on the inner wall of the sewage bucket 100 at different positions, so that after the spraying assembly 300 rotates, the circumferential range at different angles can be cleaned.

[0068] Specifically, in order to ensure that the spraying assembly 300 can clean the inner wall of the sewage bucket 100 and the sewage inlet 101, the angle between the water spraying direction of the nozzle 320 and the rotation plane of the spraying assembly 300 is greater than 0° and less than or equal to 60°. That is, 0° ≤ ∠α or ∠β or ∠γ ≤ 60° to ensure that the water outlet direction of the nozzle 320 can clean the inner side wall of the sewage bucket 100.

[0069] In some embodiments, the water outlet holes 302 penetrating through the surface of the spraying assembly body 310 have the function of dividing the fluid pressure, so that a small part of the cleaning liquid flows out from the water outlet holes 302, avoiding the large pressure of the liquid flowing in the hollow rotating shaft 330, resulting in a large impact force of the water flow on the nozzle 320 or the spraying assembly body 310, and causing uneven flow rates of the cleaning liquid flowing into each nozzle 320.

[0070] The aperture of the water outlet holes 302 on the spraying assembly body 310 is smaller than the aperture of the nozzles 301. If the aperture of the water outlet holes 302 is large, it is very likely that a large amount of the cleaning liquid in the spraying assembly body 310 flows out from the water outlet holes 302, resulting in very little cleaning liquid flowing into the nozzles 320. Further, very little liquid flows out from the nozzles 301 of the nozzles 320, and the ejected liquid column cannot be formed, and it is almost impossible to clean the inner wall of the sewage bucket 100 or the sewage inlet 101, and the cleaning purpose cannot be achieved.

[0071] In some embodiments, the sewage bucket assembly 1000 further includes a water delivery pipeline 410 and a water supply interface 420. The water delivery pipeline 410 is configured to communicate with a water source. In response to the sewage bucket 100 being installed in the sewage bucket assembly 1000, the water supply interface 420 is connected to the water delivery pipeline 410, and the water delivery pipeline 410 and the water supply interface 420 are configured to supply water to the spraying assembly 300. A sealing member is provided at the connection between the water supply interface 420 and the water delivery pipeline 410. The sealing member can be an elastic member, configured to tightly connect the water delivery pipeline 410 and the water supply interface 420 to avoid water leakage.

[0072] The included angle between the water supply direction of the water supply interface 420 and the installation direction of the sewage bucket 100 is greater than 0° and less than or equal to 90°. The cleaning liquid in the water delivery pipeline 410 flows from a lower position to a higher position, which can slow down the flow rate of the cleaning liquid. In response to the connection between the water source and the water delivery pipeline 410, the cleaning liquid provided by the water source can flow from the water delivery pipeline 410 to the water supply interface 420. When the cleaning liquid flows through the water supply interface 420, it undergoes the first deceleration. Further, it flows through the water supply interface 420 to the spraying assembly 300. As Figure 9 shown, the water supply interface 420 is connected to the spraying assembly 300 through a connecting pipeline 430. The cleaning liquid flows through the connecting pipeline 430 and enters the interior of the spraying assembly body 310 through the hollow rotating shaft 330. Since the spraying assembly body 310 is provided with water outlet holes 302, the cleaning liquid undergoes the second pressure reduction and deceleration within the spraying assembly body 310. Under the action of the liquid pressure of the cleaning liquid itself, it moves towards the direction of the nozzle 301 of the spray head 320, and finally is sprayed out from the nozzle 301 of the spray head 320 to achieve the cleaning of the inner wall of the sewage bucket 100 and the sewage inlet 101.

[0073] The second aspect of the embodiments of the present disclosure provides a cleaning device, including: the sewage bucket assembly 1000 described in any one of the first aspects of the embodiments of the present disclosure. As Figure 10 shown, the cleaning device has a clean water bucket assembly, a sewage bucket assembly 1000, and a cleaning module.

[0074] The sewage bucket assembly 1000 provided by the present disclosure includes a spraying assembly 300, and the spraying assembly 300 is arranged inside the sewage bucket 100. The inner wall of the sewage bucket 100 can be cleaned through the spraying assembly 300. In addition, since the spraying assembly 300 is arranged at the bottom of the filter assembly 200, the spraying assembly 300 can not only clean the inner side wall of the sewage bucket 100, but also clean the sewage inlet 101 of the sewage bucket 100. While improving the cleaning intensity inside the sewage bucket 100, it has the advantage of simple operation, which is beneficial to the user's convenient operation and improves the user's experience.

[0075] For the specific structures, working principles, and beneficial effects of the sewage bucket assembly and the cleaning device provided by the embodiments of the present disclosure, reference can be made to the sewage bucket assembly and the cleaning device described in any of the above embodiments, and details will not be elaborated here.

[0076] Finally, it should be noted that the embodiments in this specification are described in a progressive manner, and the key points of each embodiment are the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and the relevant parts can be referred to the descriptions in the method part.

[0077] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit it; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
