The multi-functional base station equips the floor scrubber with the function of automatic drainage and cleaning of the sewage tank, eliminating manual operation.

[0003] Although the self-cleaning function of the sewage tank of the current multifunctional base station of the floor scrubber is easy to use, it has the disadvantages of complex mechanism design, high cost, short mechanism service life, unclean cleaning, and hair easily entangled in the cleaning mechanism during self-cleaning. At present, the self-cleaning of the sewage tank of the multifunctional base station of the floor scrubber mostly adopts the following methods: the first method is to extend the water spray mechanism into the sewage tank for spray cleaning, which has a complex structural design, high manufacturing cost, and hair easily entangled in the mechanism during the cleaning process; the second method is to first inject clean water into the sewage tank, and then blow air to stir the clean water for cleaning. This cleaning method is costly and can only clean local areas, and the sewage tank is not cleaned thoroughly. Utility Model Content

In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0035] See also Figures 1 to 6 As shown, the embodiment of the present application provides a water spraying member, which is at least used to clean the sewage bucket 30. The sewage bucket mentioned here can be a cleaning device, such as a floor scrubber or a sewage bucket of a cleaning base station.

[0036] Specifically, the water spray part in this embodiment includes a water spray body 10, which includes a conical column. 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 is provided with a accommodating cavity 111 and a spray hole 112. The spray hole 112 is arranged on the outer side wall of the water spray body 10 and is connected with the accommodating cavity 111; wherein, the extension line of the spray hole 112 is offset from the central axis A of the water spray body 10.

[0037] It is understandable that the conical column in this embodiment can be a frustum (i.e., a structure in which the cone tip is removed) or a cone. Figure 1 to Figure 2 In addition, the "outer wall" in "the spray hole 112 is arranged on the outer wall of the water spray body 10" in this embodiment can be the outer peripheral side surface 113 of the water spray body 10, or the bottom side wall or the top side wall of the water spray body 10.

[0038] In actual use, the water spray body 10 is rotatably connected to the top of the sewage bucket 30. When the sewage bucket 30 needs to be cleaned, the water spray body 10 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, and the water entering the accommodating chamber 111 can be sprayed out from the spray hole 112, so as to clean the inner wall surface of the sewage bucket 30.

[0039] In the present application, since the extension line of the spray hole 112 is offset from the central axis A of the water spray body 10, that is, the extension line of the spray hole 112 does not intersect with the central axis A of the water spray body 10. In this way, when water is ejected from the spray hole 112, a recoil force can be applied to the water spray body 10, and the direction of the recoil force is offset from the central axis A of the water spray body 10, so that the water spray body 10 can rotate, and then the spray hole 112 can rotate and spray water along the outer circumference of the water spray body 10, and finally the inner wall surface of the sewage bucket 30 can be effectively cleaned. 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.

[0040] At the same time, since the water spray body 10 in this embodiment is a conical column, the outer peripheral side surface 113 of the conical column is an inclined surface inclined toward the central axis A of the water spray body 10. After the water spray body 10 is installed, the thinner end of the conical column is arranged toward the bottom of the sewage bucket 30. In this way, when the water spray body 10 cleans the sewage bucket 30, the hair attached to the water spray body 10 can slide down under the action of its own gravity, and the hair is not easy to be entangled on the water spray body 10, and it is not easy for the injection hole 112 to be blocked, which can improve the cleaning efficiency and cleaning effect of the water spray component in this embodiment on the sewage bucket 30.

[0041] Furthermore, the water spray body 10 in this embodiment can be an integrated structure or a conical column formed by a plurality of bodies, which is not specifically limited in this application. In actual processing, the edges of the conical column are provided with rounded corners to prevent the conical column from scratching the human body or other structures during installation and use.

[0042] Optionally, the spray hole 112 in this embodiment can be one or more, that is, two or more. In this application, it is preferred to adopt the situation where the spray hole 112 is set to be multiple. Along the direction of the central axis A of the water spray body 10, the projections of the multiple spray holes 112 all extend in the clockwise direction or in the counterclockwise direction (see Figure 3 As shown, Figure 3The dotted line is the circumferential direction of the water spray body 10, and the solid line is the extension direction of the spray hole 112). That is to say, along the circumferential direction of the water spray body 10, the deflection directions of the multiple spray holes 112 are consistent, that is, they are either all deflected in the clockwise direction or all deflected in the counterclockwise direction. In this way, when the spray holes 112 spray water, the direction of the recoil force exerted by the water on the water spray body 10 can also be arranged in the counterclockwise direction or the clockwise direction. In this way, the water spray body 10 can be rotated quickly, thereby improving the cleaning effect and cleaning efficiency of the water spray part on the sewage bucket 30.

[0043] Furthermore, in the present embodiment, a plurality of spray holes 112 are provided, which not only can increase the recoil force exerted on the water spray body 10 when the spray holes 112 spray water, but also can increase the water spraying area and water spraying amount of the water spraying part, thereby further improving the cleaning effect and cleaning efficiency of the water spraying part in the present embodiment.

[0044] Furthermore, at least some of the multiple spray holes 112 in this embodiment have different spray directions. Thus, the multiple spray holes 112 can spray water columns 40 in different directions, thereby fully cleaning the inner wall surface of the sewage bucket 30 .

[0045] For example, in some embodiments of the present application, a portion of the spray holes 112 sprays the water column 40 toward the top surface of the sewage bucket 30, a portion of the spray holes 112 sprays the water column 40 toward the top side wall of the sewage bucket 30, and another portion of the spray holes 112 sprays the water column 40 toward the bottom surface or bottom side wall of the sewage bucket 30. As long as the deformation method is based on the concept of the present application, it is within the protection scope of the present application.

[0046] Combination Figure 1 to Figure 2 As shown, the water spray body 10 in this embodiment is provided with a hollow portion 114, and the provision of the hollow portion 114 can reduce the overall weight of the water spray body 10. In this way, when the spray hole 112 sprays water, only a small recoil force is required to rotate the water spray body 10, which can improve the rotation response efficiency of the water spray member in this embodiment.

[0047] Furthermore, the accommodating chamber 111 in the present embodiment includes an annular cavity portion 1111, which is arranged to extend along the outer circumference of the water spraying body 10, and the spray hole 112 is connected to the annular cavity portion 1111. In other words, the accommodating chamber 111 does not fill the internal space of the water spraying body 10 as a whole, but is only arranged at the outer circumference of the water spraying body 10, so that the internal capacity of the accommodating chamber 111 can be further reduced, and the weight of the water spraying body 10 during operation can be further reduced. At the same time, the water in the accommodating chamber 111 can be quickly transported to the spray hole 112, thereby further improving the rotation response time of the water spraying body 10 in the present embodiment.

[0048] Combination Figures 1 to 4 As shown, in order to facilitate connection, a connecting portion 12 is provided in the hollow portion 114 in this embodiment, and a guide channel 11 is provided on the connecting portion 12. The guide channel 11 is connected to the annular cavity portion 1111 to facilitate the transportation of water into the annular cavity portion 1111.

[0049] Exemplarily, the connection portion 12 in this embodiment includes a connection column 121 and a delivery column 122, the central axis of the connection column 121 is consistent with the central axis A of the water spray body 10, and there are multiple delivery columns 122, and the multiple delivery columns 122 are arranged along the outer periphery of the connection column 121 and extend along the radial direction of the connection column 121, and the two ends of each delivery column 122 are respectively connected to the connection column 121 and the inner side wall of the hollow portion 114. The diversion channel 11 includes an input section 1101 and an output section 1102 that are interconnected, the input section 1101 is arranged on the connection column 121 and extends along the length direction of the connection column 121, and the output section 1102 is arranged on the delivery column 122 and extends in the length direction of the delivery column 122. With such an arrangement, external water can be transported from the delivery column 122 to the annular cavity portion 1111 via the connection column 121.

[0050] Of course, in other embodiments of the present application, the guide channel 11 for conveying water to the annular cavity 1111 may also extend in other directions. As long as it is other deformation methods based on the concept of the present application, it is within the protection scope of the present application.

[0051] Optionally, the hollow portion 114 in this embodiment may penetrate the water spray body 10 along the length direction of the water spray body 10, or may not penetrate the water spray body 10 along the length direction of the water spray body 10, which is not specifically limited in this application.

[0052] See also Figures 5 and 6 As shown, the present application also provides a cleaning component, which includes a rotating connection 20 and a water spray component. The water spray component is connected to the rotating connection 20 and can rotate relative to the rotating connection 20, and the water spray component is the water spray component in the above-mentioned embodiment. Therefore, the cleaning component includes all the technical effects of the water spray component in the above-mentioned embodiment.

[0053] In actual use, the cleaning component is connected to the top of the sewage bucket 30 through the rotating connector 20, and the rotating connector 20 is connected to the pump body and the water source. The rotating connector 20 is provided with a channel connected to the accommodating chamber 111. 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 injection hole 112, thereby cleaning the inner wall surface of the sewage bucket 30.

[0054] Since the extension line of the spray hole 112 of the water spray member is offset from the central axis A of the water spray body 10, that is, the extension line of the spray hole 112 does not intersect with the central axis A of the water spray body 10. In this way, when water is ejected from the spray hole 112, a recoil force can be applied to the water spray body 10, and the direction of the recoil force is offset from the central axis A of the water spray body 10, so that the water spray body 10 can rotate relative to the rotating connector 20, and then the spray hole 112 can be rotated along the outer periphery of the water spray body 10 to spray water, and finally the inner wall surface of the sewage bucket 30 can be effectively cleaned.

[0055] For example, in some embodiments of the present application, the rotary 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 bend-through type, or a double bend-through type), or a rotary joint without a bearing.

[0056] Combination Figures 1 to 6 As shown, the present application also provides a sewage bucket 30, which includes a barrel body 31, a cover body 32 and a cleaning assembly, wherein the cover body 32 is arranged on the top of the barrel body 31; the cleaning assembly is the above-mentioned cleaning assembly, which is connected to the cover body 32 through the above-mentioned rotating connector 20.

[0057] 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.

[0058] In the present application, the extension line of the spray hole 112 of the water spray part is offset from the central axis A of the water spray body 10, that is, the extension line of the spray hole 112 does not intersect with the central axis A of the water spray body 10. In this way, when water or the like is ejected from the spray hole 112, a recoil force can be applied to the water spray body 10, and the direction of the recoil force is offset from the central axis A of the water spray body 10, so that the water spray body 10 can rotate, and then the spray hole 112 can rotate and spray water along the outer circumference of the water spray body 10, and finally the inner wall surface of the sewage bucket 30 can be effectively cleaned. At the same time, since the water spray body 10 in this embodiment is a conical column, in this way, when the water spray body 10 cleans the sewage bucket 30, hair or the like is not easy to be entangled on the water spray body 10, and the spray hole 112 is not easy to be blocked, which can improve the cleaning efficiency and cleaning effect of the water spray part in this embodiment on the sewage bucket 30, and the structure is simple and maintenance is convenient.

[0059] According to the above embodiments, it can be known that:

[0060] The water spray body 10 of the present application is a conical structure. In actual design, the water spray body 10 can be designed into a small radius structure with simple structure, convenient installation, high energy utilization efficiency, small space occupation, low production cost, and can effectively prevent hair entanglement and achieve good self-cleaning effect.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.
