[0034] See also Figures 1 to 9 As shown, according to an embodiment of the present application, a sewage bucket 30 is provided. In this embodiment, the sewage bucket can be a sewage bucket 30 of a floor scrubber or a cleaning base station.

[0035] See also Figure 3 , Figure 6 as well as Fig. 9 As shown, the sewage bucket 30 in this embodiment includes a barrel body 31, a cover body 32 and a cleaning assembly. The cover body 32 in this embodiment is arranged on the top of the barrel body 31; the cleaning assembly is arranged on the cover body 32. In actual work, the sewage bucket 30 can be cleaned by the cleaning assembly.

[0036] Combination Figures 1 to 9 As shown, the cleaning assembly in this embodiment includes a water spray body 10. When in use, the water spray body 10 is at least used to be installed on the top of the inner side of the sewage bucket 30. The water spray body 10 has a water spray column 11. After installation, the water spray body 10 protrudes from the bottom of the cover body 32 and is located in the barrel body 31. The water spray body 10 is provided with a receiving cavity 111 and a spray hole 112. The spray hole 112 is provided on the outer side wall of the water spray column 11 and communicates with the receiving cavity 111.

[0037] The cleaning assembly in this embodiment mainly includes a water spray column 11. When actually used, the water spray body 10 only needs to be installed on the inner top of the sewage bucket 30, and water can enter the accommodating cavity 111, and then spray out from the spray hole 112 to clean the inner wall surface of the sewage bucket 30. The cleaning assembly in this embodiment has a simple structure and high manufacturing cost, and the columnar design of the water spray column 11 is not easy to entangle hair, and is safe and reliable to use.

[0038] In this application, along the first direction, i.e. Figure 1 , Figure 4 as well as Figure 7In the H direction shown in , the outer peripheral side surface 113 of the water spray column 11 includes one of a vertical surface or an inclined surface, wherein the inclined surface is an inclined surface inclined toward the central axis A of the water spray column 11. It can be understood that the water spray column 11 in this embodiment is a portion of the water spray body 10 protruding from the side of the cover body 32 close to the barrel body 31. The "outer side wall" in the "injection hole 112 is provided on the outer side wall of the water spray column 11" in this embodiment can be the outer peripheral side surface 113 of the water spray column 11, or it can be the bottom side wall or the top side wall of the water spray column 11. The vertical plane in this embodiment refers to a plane in which all straight lines are parallel to the central axis of the water spray column 11 when drawn in the plane along the first direction.

[0039] When the sewage bucket 30 needs to be cleaned, the cleaning component is connected to the pump body and the water source. When the pump body is working, water can be pumped into the accommodating chamber 111. The water entering the accommodating chamber 111 can be sprayed out from the spray hole 112, thereby cleaning the inner wall surface of the sewage bucket 30.

[0040] In addition, along the up and down directions of the sewage bucket 30, the outer peripheral side surface 113 of the water spray column 11 can be a vertical surface or an inclined surface. In this way, when the cleaning component cleans the sewage bucket 30, hair and the like are not easy to be entangled in the water spray column 11, and the spray hole 112 is not easy to be blocked, which can improve the cleaning efficiency and cleaning effect of the cleaning component in this embodiment on the sewage bucket 30 and the like.

[0041] Optionally, the water spray column 11 in this embodiment includes a cylindrical or conical column. In this embodiment, by setting the water spray column 11 as a cylindrical or conical column, compared with other structures, such as a sphere, the surface of the cylindrical or conical column has a certain extension direction, a flat surface, and a simple structure, which can effectively prevent hair and the like from being entangled in the water spray column 11. Specifically, the present application Figures 1 to 3 , Figures 7 to 9 The figures all show the situation when the water spray column 11 is a cylinder. Figures 1 to 3 In the embodiment, the water spraying body 10 is arranged in a cylindrical shape. Figures 7 to 9 In the embodiment, the water spraying body 10 is a bottle-shaped structure, and the water spraying column 11 is the cylindrical part of the bottle-shaped structure. Figures 4 to 6 FIG. 1 shows a case where the water spray body 10 is arranged in a conical column. Figures 4 to 6 In the figure, the cross section of the conical column gradually decreases along the H square, that is, the distance from the outer peripheral side surface 113 of the conical column to the central axis A of the conical column gradually decreases along the H direction. This arrangement can not only effectively prevent hair from being entangled on the conical column, but also make the hair attached to the surface of the conical column fall off along the surface of the conical column.

[0042] It is understandable that in order to prevent hair from being entangled in the water spray column 11, in other embodiments of the present application, the water spray column 11 can also be set as a prism, a pyramid, etc., as long as the outer peripheral side surface 113 of the water spray column 11 is a smooth surface that is flat and has a straight extension direction.

[0043] During actual processing, the water spray body 10 in this embodiment can be formed by surrounding multiple main structures, or it can be an integrally formed structure. As long as it is other deformation methods based on the concept of this application, it is within the protection scope of this application.

[0044] Recombination Figures 1 to 9 As shown, in order to facilitate the connection of the water spray body 10 to the sewage bucket 30, a connecting head 20 is provided on the water spray body 10 in this embodiment, and a channel connected to the accommodating chamber 111 is provided on the connecting head 20. In actual use, the pump body, the water source and the connecting head 20 are connected by a pipeline, so that external water can be transported to the accommodating chamber 111, and finally ejected through the injection hole 112 to clean the sewage bucket 30.

[0045] For example, in some embodiments of the present application, the connector 20 includes a rotary joint, the water spray body 10 is rotatably connected to the rotary joint, and the axis of the water spray body 10 is consistent with the axis of the rotary joint. In this way, the water spray body 10 can rotate relative to the rotary joint, and then the spray hole 112 can be rotated along the outer circumference of the water spray body 10 to spray water, so as to effectively clean the inner wall surface of the sewage bucket 30. The rotary joint in this embodiment can be a rotary joint with a bearing (such as a straight-through type, a curved-through type, or a double curved-through type), or a rotary joint without a bearing.

[0046] In actual operation, the cleaning assembly of the present application can be provided with a driving structure (such as a driving motor or other structure) to drive the water spray body 10 to rotate, or the water spray body 10 can be structurally designed to rotate the water spray body 10. In order to reduce the production and maintenance costs of the sewage bucket 30, it is preferred in the present application to rotate the water spray body 10 without providing a driving structure.

[0047] Specifically, in order to make the water spray body 10 rotate during operation, the extension line of the spray hole 112 is designed to be offset from the central axis A of the water spray column 11, that is, the extension line of the spray hole 112 does not intersect with the central axis A of the water spray column 11. In this way, when water is ejected from the spray hole 112, a recoil force can be applied to the water spray column 11, and the direction of the recoil force is offset from the central axis A of the water spray column 11, so that the water spray body 10 can rotate relative to the rotary joint, and then the spray hole 112 can rotate along the outer periphery of the water spray body 10 to spray water, and finally effectively clean the inner wall surface of the sewage bucket 30. It can be seen that this embodiment can use the recoil force generated during the water spraying process to drive the water spray body 10 to rotate, with high energy utilization and low production cost.

[0048] Optionally, the spray holes 112 in this embodiment include multiple ones, and at least some of the spray holes 112 have different extension directions. In this way, the spray holes 112 can spray water columns 40 in different directions, thereby fully cleaning the inner wall surface of the sewage bucket 30.

[0049] For example, in some embodiments of the present application, a portion of the spray holes 112 sprays the water column 40 toward the cover body 32, a portion of the spray holes 112 sprays the water column 40 toward the top side wall of the barrel body 31, and another portion of the spray holes 112 sprays the water column 40 toward the bottom surface or bottom side wall of the barrel body 31. As long as it is a deformation method based on the conception of the present application, it is within the protection scope of the present application.

[0050] Furthermore, the accommodating cavity 111 in this embodiment includes an annular cavity portion 1111 and a connecting portion 1112, wherein the annular cavity portion 1111 is arranged along the outer circumference of the water spray column 11 and is connected to an external water source through the connecting portion 1112. The annular cavity portion 1111 extends along the circumference of the water spray column 11, and a hollow portion 114 is arranged inside the annular cavity portion 1111, and the spray hole 112 is connected to the annular cavity portion 1111. In other words, the provision of the hollow portion 114 in this embodiment can reduce the overall weight of the water spray body 10.

[0051] In this way, when the spray hole 112 sprays water, only a very small recoil force is needed to cause the water spray body 10 to rotate, which can improve the rotation response efficiency of the cleaning component in this embodiment.

[0052] At the same time, in this embodiment, the annular cavity portion 1111 extends along the circumference of the water spray column 11, that is to say, the accommodating chamber 111 does not fill the internal space of the water spray column 11 as a whole. In this way, the internal capacity of the accommodating chamber 111 can be reduced, and the weight of the water spray column 11 during operation can be further reduced. At the same time, the water in the accommodating chamber 111 can be quickly transported to the injection hole 112, thereby further improving the rotation response time of the water spray body 10 in this embodiment.

[0053] Further, the hollow portion 114 in this embodiment is at least partially located at the bottom of the water spray body 10 (the end facing the bottom of the barrel 31), and the hollow portion 114 located at the bottom of the water spray body 10 includes a cylindrical cavity, a prismatic cavity, or a conical cavity, and the axis of the cylindrical cavity, the prismatic cavity, or the conical cavity is consistent with the axis of the water spray column 11, and when the hollow portion 114 is a conical cavity, along the first direction, that is, the H direction, the distance from the peripheral wall surface of the conical cavity to the central axis of the water spray column 11 gradually increases. Such a configuration can prevent the hollow portion 114 from having corners, thereby avoiding the phenomenon of dirt and grime in the hollow portion.

[0054] Of course, in other embodiments of the present application, the hollow portion 114 can also be arranged at the top of the water spray body 10 (away from the bottom of the barrel body 31). When the hollow portion 114 is located at the top of the water spray body 10, since the connection between the hollow portion 114 and the cover body 32 is blocked, there will be no problem of hiding dirt and grime. Therefore, there is no specific limitation on its structural shape, as long as it can lighten the water spray body 10 and improve the rotation response speed of the water spray body 10.

[0055] According to the above embodiments, it can be known that:

[0056] The water spray column 11 of the present application adopts a cylindrical, bottle-shaped or conical structure, and a smooth outer surface is used to prevent hair entanglement; the design of the rotating joint can greatly reduce the pressure loss of the entire flow channel system, thereby increasing the spray pressure of the water spray port and achieving a better spraying effect (boosting the efficiency of the pump or external water pressure source); in actual design, the water spray column 11 in this embodiment can be designed as a small radius structure, so that the torque of the water spray column 11 is relatively small, and the use of a rotating joint with a bearing can reduce the rotational friction, so that self-rotation can still be achieved.

[0057] It can be seen that the cleaning component of the present application has a simple structure, is easy to install, has high energy utilization efficiency, occupies a small space, has a low production cost, and can effectively prevent hair entanglement and achieve a good self-cleaning effect.

[0058] On the other hand, the present application also provides a cleaning device. Exemplarily, the cleaning device may be, for example, a floor scrubber or a cleaning base station. The cleaning device includes a water tank (not shown in the figure), a sewage bucket 30, and a pump body (not shown in the figure). The sewage bucket 30 is the sewage bucket 30 in the above embodiment. The pump body is arranged outside the sewage bucket 30 and is connected to the water tank to pump the water in the water tank to the accommodating chamber 111. Since the cleaning device in this embodiment includes the sewage bucket 30 in the above embodiment, the cleaning device includes all the technical effects of the above sewage bucket 30. Since the technical effects of the sewage bucket 30 have been described in detail above, they will not be repeated here.

[0059] In this embodiment, when the sewage bucket 30 needs to be cleaned, the pump body can be controlled by using a controller of the cleaning device, and the pump body can work to pump the water in the water tank to the sewage bucket 30. After the water in the water tank enters the cleaning component of the sewage bucket 30, it can enter the accommodating cavity 111 and finally be sprayed out from the spray hole 112 to clean the inner wall surface of the sewage bucket 30. In this process, the water spraying body 10 receives the reaction force of the water sprayed from the spray hole 112, and can rotate around the rotating structure, and the water sprayed from the spray hole 112 can be sprayed more comprehensively to the inner wall surface of the sewage bucket 30, and finally the sewage bucket 30 can be quickly cleaned.

[0060] In addition, in this embodiment, the pump body can be set on the sewage bucket 30, or can be set on a part other than the sewage bucket 30. It can be installed according to actual design and usage requirements, and is not specifically limited in this application.

[0061] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0062] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
