Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0028] Before further describing the embodiments of the present invention in detail, the orientation terms involved in the embodiments of the present invention, such as "upper part", "lower part", and "side part", are based on Figure 1 the orientation shown in, and do not have the meaning of limiting the protection scope of the present invention.

[0029] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the drawings.

[0030] As Figure 1 shown, the present application provides a sewage suction structure, which is applied to a charging station of a floor sweeper, including: a water suction pipe 1, and a plurality of notches 11 are provided at the pipe orifice of the water suction pipe 1, as Figure 2 shown. A sewage tray 3, the pipe orifice of the water suction pipe 1 is located in the sewage tray 3, the bottom of the sewage tray 3 and the pipe orifice of the water suction pipe 1 are arranged opposite to each other, and the bottom of the sewage tray 3 is inclined downward. By providing a plurality of notches 11 at the pipe orifice of the water suction pipe 1 and inclining the bottom of the sewage tray 3 downward at the same time, it is beneficial to the collection of sewage and the suction of the water suction pipe 1, facilitating the complete drainage of sewage and reducing the suction noise.

[0031] Preferably, at least three notches 11 are provided, and at least three notches 11 are circumferentially and uniformly arranged around the axis of the pipe orifice of the water suction pipe 1.

[0032] Preferably, the notch 11 is triangular or square or arc-shaped. By providing a plurality of notches 11 at the pipe orifice, the contact area between the pipe orifice and the bottom of the tray is reduced, the flow area between the pipe orifice and the sewage is increased, and the water suction capacity of the pipe orifice is improved.

[0033] In one embodiment, the pipe orifice is disposed adjacent to the lowest point of the bottom of the sewage tray 3 so that the pipe orifice is submerged in the sewage. Preferably, the pipe orifice of the water suction pipe 1 is disposed at the lowest point of the bottom of the sewage tray 3 to maximize the submergence of the pipe orifice, reduce the residual water in the sewage tray 3, and avoid generating noise during water suction.

[0034] In one embodiment, the bottom of the sewage tray 3 is funnel-shaped. This is conducive to the collection of sewage, facilitates the suction of the water suction pipe 1, reduces the residual water in the sewage tray 3, and the centrally collected sewage easily submerges the pipe orifice, avoiding generating sharp noise when sucking sewage.

[0035] As Figure 3 shown, the thickness of the bottom of the sewage tray 3 gradually decreases from the outer edge of the bottom to the direction of the pipe orifice of the water suction pipe 1. That is to say, the lower surface of the bottom of the sewage tray 3 is a plane, ensuring the stability of the installation of the sewage tray 3, and the upper surface of the bottom of the sewage tray 3 is an inclined curved surface, and the inclined curved surface inclines from the outer edge of the bottom of the sewage tray 3 to the direction of the pipe orifice of the water suction pipe 1. From Figure 3 the cross-section of the sewage tray 3, it can be seen that the thickness between the upper surface and the lower surface of the bottom of the sewage tray 3 at the outer edge of the bottom is greater than the thickness between the upper surface and the lower surface of the bottom of the sewage tray 3 at the pipe orifice of the water suction pipe 1.

[0036] Preferably, as Figure 3 and Figure 4 shown, the sewage structure further includes a filter plate 2. The filter plate 2 is disposed on the sewage tray 3, and the pipe orifice of the water suction pipe 1 is disposed between the filter plate 2 and the bottom of the sewage tray 3. The filter plate 2 is provided with a clamping seat 21, and the sewage tray 3 is provided with a clamping claw 31, and the clamping seat 21 and the clamping claw 31 are clamped. Sewage flows into the sewage tray 3 through the filter plate 2, preventing impurities in the sewage from clogging the water suction pipe 1. The size of the filter holes on the filter plate 2 can be set according to requirements. Preferably, the diameter of the filter holes is less than one-half of the diameter of the pipe orifice of the water suction pipe.

[0037] Preferably, in one embodiment, the sewage structure further includes a liquid level detection member and a control unit. The liquid level detection member is disposed in the sewage tray 3. The liquid level detection member and the water suction pipe 1 are electrically connected to the control unit respectively. The control unit is used to control the water suction pipe 1 to start or stop water suction according to the feedback information of the liquid level detection member. When the water level in the sewage tray 3 detected by the liquid level detection member reaches the first water level, the control unit controls the water suction pipe 1 to start water suction. When the water level in the sewage tray 3 detected by the liquid level detection member reaches the second water level, the control unit controls the water suction pipe 1 to stop water suction. The first water level is higher than the second water level. The first water level is the highest water level of the sewage tray 3, and the second water level is the lowest water level of the sewage tray 3. The control unit prevents the water in the sewage tray 3 from overflowing, and also ensures that the sewage submerges the pipe orifice, preventing sharp noise from being generated when the water suction pipe 1 sucks water.

[0038] Preferably, in another embodiment, the sewage suction structure further includes a control unit, in which a timing module is provided. There is an electrical connection between the water suction pipe 1 and the control unit. The control unit is configured to control the water suction pipe 1 to start or stop sucking water according to the feedback information of the timing module. A first time is set in the timing module. After the sewage discharge starts, the control unit is configured to control the water suction pipe 1 to start sucking water after the first time, and after sucking water for the first time, the control unit controls the water suction pipe 1 to stop sucking water, and so on until the sewage discharge ends.

[0039] In this embodiment, a charging station for a floor cleaning machine is further provided, on which a sewage suction structure as described above is provided.

[0040] As Figure 3 and Figure 4 As shown, a cleaning disk 4 is provided in the charging station for the floor cleaning machine. There are two cleaning disks 4, and the two cleaning disks 4 are used to clean the mop on the floor cleaning machine. The sewage generated after the cleaning disk 4 cleans the mop flows into the sewage tray 3 through the filter plate 2. The bottom of the sewage tray 3 is inclined downward, and the water suction pipe 1 located at the lowest point of the bottom of the sewage tray 3 sucks the sewage to the outside of the charging station for the floor cleaning machine. In this embodiment, the bottom of the sewage tray 3 is an inclined curved surface, which is convenient for collecting sewage. The pipe orifice of the water suction pipe 1 is located at the lowest point of the bottom of the sewage tray 3, which is beneficial to submerge the pipe orifice with sewage. A plurality of notches are provided at the pipe orifice of the water suction pipe 1, which increases the flow area of the sewage, avoids generating noise during water suction, and also reduces the residual water in the sewage tray 3.

[0041] In the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.

[0042] Those skilled in the art will readily think of other implementation schemes of the present utility model after considering the specification and practicing the present utility model disclosed herein. The present utility model is intended to cover any variations, uses or adaptations of the present utility model, which follow the general principles of the present utility model and include the common general knowledge or conventional technical means in the technical field not disclosed by the present utility model.
